            <content:encoded><![CDATA[<p>Some of the most important fintech changes are happening in the boring stuff — security systems, business payments, regulatory compliance. These trends are quietly reshaping how finance actually works.</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*xi7Mq2D1qye-9YzrdlO29Q.png" /></figure><h3>1. Behavioural Biometrics</h3><p>The financial industry is experiencing a shift from static biometric authentication methods like fingerprints and Face ID to behavioral authentication systems.</p><p>This new approach enables continuous monitoring of thousands of behavioral parameters throughout an entire user session, rather than just authenticating at the point of login. The technology creates no additional friction for users while simultaneously making it significantly more difficult for fraudsters to bypass security measures.</p><p><em>Further reading:</em></p><ul><li><a href="https://www.ibm.com/think/topics/behavioral-biometrics"><em>What is behavioral biometrics?</em></a><em> (IBM)</em></li><li><a href="https://www.linkedin.com/pulse/behavioral-biometrics-latest-enhancement-fintech-kazi-monirul-kabir-9q3ee/"><em>Behavioral Biometrics: The latest enhancement in Fintech Security</em></a><em> (LinkedIn)</em></li><li><a href="https://seon.io/resources/behavioral-biometrics-against-fraud/"><em>Behavioral Biometrics: What Is It &amp; How It Works Against Fraud</em></a><em> (Seon)</em></li><li><a href="https://mojoauth.com/ciam-101/behavioral-biometrics-continuous-authentication#what-is-behavioral-biometrics"><em>Enhancing Security with Behavioral Biometrics and Continuous Authentication</em></a><em> (MojoAuth)</em></li></ul><h3>2. Virtual Corporate Cards in B2B</h3><p>Businesses are increasingly adopting virtual banking cards as their preferred payment method, driven by the unique capabilities these digital solutions offer.</p><p>Virtual cards provide single-use functionality and can be instantly deactivated when needed, offering unprecedented security control. Companies can implement precise budget control through merchant and MCC code restrictions, along with time-based limitations.</p><p>Additionally, real-time monitoring capabilities provide immediate transaction notifications, enabling finance teams to maintain complete oversight of corporate spending.</p><p><em>Further reading:</em></p><ul><li><a href="https://www.juniperresearch.com/press/b2b-spending-to-dominate-global-virtual-cards-market/"><em>B2B Spending to Dominate Global Virtual Cards Market, Accounting for 83% of Market Value by 2029</em></a><em> (Juniper Research)</em></li><li><a href="https://www.mastercard.com/us/en/news-and-trends/Insights/2024/virtual-cards-101-simplifying-commercial-payments.html"><em>Virtual cards 101: Simplifying commercial payments</em></a><em> (MasterCard)</em></li><li><a href="https://www.mastercard.com/global/en/business/large-enterprise/mastercard-corporate-solutions/the-state-of-commercial-card-acceptance-2025-white-paper.html"><em>The state of commercial card acceptance 2025</em></a><em> (MasterCard)</em></li><li><a href="https://coinlaw.io/virtual-credit-card-statistics/"><em>Virtual Credit Card Statistics 2025: Adoption Rates and Market Growth</em></a><em> (Coinlaw)</em></li></ul><h3>3. Local Payment Methods Dominance</h3><p>Local payment methods have become essential for businesses operating in emerging markets where traditional cards are less commonly used, as adding relevant regional payment options directly increases conversion rates.</p><p>The impact on customer behavior is substantial: up to 60% of users will abandon their checkout process if their preferred payment method is unavailable. This trend is particularly pronounced among younger demographics, with 63% of shoppers under 45 making purchases from international retailers. The likelihood of completing these cross-border transactions increases significantly when customers see their preferred payment methods and pricing displayed in their local currency.</p><p><em>Further reading:</em></p><ul><li><a href="https://stripe.com/blog/testing-the-conversion-impact-of-50-plus-global-payment-methods"><em>Testing the conversion impact of 50+ global payment methods</em></a><em> (Stripe)</em></li><li><a href="https://www.notion.so/2025-261417b6ff008003bafbdd5a60fec811?pvs=21"><em>112 payment industry statistics for 2025: Trends, costs, methods, and more</em></a><em> (Gr4vy)</em></li><li><a href="https://primer.io/blog/top-reasons-for-cart-abandonment-and-how-to-address-them"><em>How to reduce cart abandonment</em></a><em> (Primer)</em></li><li><a href="https://www.checkout.com/blog/payment-industry-trends"><em>7 payent trends for 2025</em></a><em> (Checkout)</em></li></ul><h3>4. Regtech Evolution</h3><p>The regulatory technology landscape is undergoing significant transformation through the deployment of AI-powered compliance agents that help organizations answer complex regulatory questions and identify compliance gaps.</p><p>Real-time automated monitoring systems are now capable of detecting suspicious money laundering operations as they occur. Regulators have raised their expectations, now requiring documented descriptions of algorithmic behavior for credit scoring, fraud detection, and pricing models.</p><p>Banking gamification mechanics are attracting increased regulatory scrutiny due to concerns about impaired decision-making processes and potential addiction risks. Meanwhile, there’s growing focus on combating dark patterns in financial services through ethical design approaches like Dopamine Banking, with the potential implementation of comprehensive regulation such as the EU Digital Fairness Act.</p><p><em>Further reading:</em></p><ul><li><a href="https://www.innreg.com/blog/fintech-regulation-guide-for-startups"><em>2025 Fintech Regulation Guide for Startups</em></a><em> (InnReg)</em></li><li><a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4568640"><em>The Gamification of Banking</em></a><em> (SSRN)</em></li><li><a href="https://www.europarl.europa.eu/RegData/etudes/ATAG/2025/767191/EPRS_ATA(2025)767191_EN.pdf"><em>Regulating dark patterns in the EU: Towards digital fairness</em></a><em> (European Comission)</em></li></ul><img src="https://medium.com/_/stat?event=post.clientViewed&referrerSource=full_rss&postId=8c686e7739ea" width="1" height="1" alt="">]]></content:encoded>

            <content:encoded><![CDATA[<figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*xieHMwBB2CIYA0yffaB7tg.png" /></figure><p><strong>Helisport Federation requested our assistance in creating a system of electronic judging.</strong></p><p>Helisport competitions involve execution of several events. One of the most complicated is<em> the Precision Flight</em>. The task is to fly a certain stretch (corridor) within a set time, carrying an attached load (a beacon) so that the beacon doesn’t cross the corridor’s vertical and horizontal boundaries. In addition to this, the competing team has to perform a number of other elements such as turns, 360º turnaround, sideways and backwards flight, etc.</p><p>Prior to the start, each team has 300 points. This is the maximum result that the team may get if it avoids all the fines. The event’s result is calculated by subtracting the sum of fines from 300 points.</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/800/1*FHvzsnRdFZSN617GyYosmQ.gif" /></figure><p>The two main reasons for creation of the electronic judgement system were as follows:</p><ol><li>To minimize the human error factor, because at that moment the judges had to eyeball whether the helicopter’s beacon crossed the corridor’s boundaries. This obviously created many mistakes, inaccuracies, and disputes.</li><li>The audience was bored because at a distance of 300 m from the competition area they couldn’t see and understand how well the team was executing the event.</li></ol><p>Plus, we were tasked with solving two other problems:</p><p>The lack of real data — when we started developing interface, the tracking system wasn’t yet operational, and we couldn’t receive the beacon’s coordinates in three-dimensional space.</p><p>The absence of starting point and complete uncertainty — we were solving a unique problem, and we have yet to find any precedents or alternatives.</p><h3><strong>Collecting information</strong></h3><p>On a sunny day in May, we flew to the aerodrome and spent a whole day there, watching the competitions together with the audience. It was important to understand what the audiences see during the events, and what happens at the briefings’ hall and beyond.</p><p>We went through dozens of different broadcasting interfaces — from aeromodelling to yachting — studying the principles of displaying various data points.</p><p>We learned by heart the massive volume with competition regulations detailing the rules of event performance. The Precision Flight event has several dozens of penalties, and we had to make sure that the interface took all of them into account — even something as small as the helicopter’s open sliding window:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*0K0zf1ArPxeBDA-0jS5fig.png" /><figcaption>Rulebook of Precision Flight: Violation penalty points</figcaption></figure><p>Happily, we were provided with a mentor on all the issues of event execution — Andrei Orekhov, master of helispor, — whose mastery of this event is truly uncanny. Thanks to Andrei, we learned all the subtleties that you won’t find in the books.</p><p>In order to collect all the requirements and to document them, we divided the event’s broadcast into components and described each of them:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*11nJO-iKkoVI7W2FBgw48A.png" /><figcaption>Components to display on broadcasting screen</figcaption></figure><h3><strong>First iteration</strong></h3><p>We decided that the video broadcast is the principal task here, while the graphics are secondary. On the other hand, the graphics had to be an independent component that reflected the essence of the event.</p><p>Our graphics’ principal components would be the visual elements that reflected the beacon’s position relative to the corridor.</p><p>The first element is responsible for the corridor’s height, and the second — for its width. Each element has its own counter of penalties that switches on if the beacon ends up outside of the set corridor.</p><p>Each tenth of a second that the beacon is flying outside of the corridor means one tenth of a point taken off as a penalty.</p><p>In the first approximation it looked like this:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*vDBYIZIaQHKhBrFAEf50vw.png" /><figcaption>First UI prototype</figcaption></figure><p>It was difficult to judge the interface’s behavior using static pictures, and so we decided to develop an interactive prototype. We wanted to make sure that events on the screen could be comprehended even by those who were watching the broadcast for the first time in their lives, unfamiliar with the event’s rules.</p><h3><strong>Prototype</strong></h3><p>Since the beacon tracking system was still under development, we had no real data to use in creating the prototype.</p><p>In order to imitate helicopter’s flight in three-dimensional space, we used the Leap Motion controller. It’s a small device that reads the palm’s movement in space and conveys its coordinates. Fortunately, Leap Motion SDK contains a JavaScript library that we connected to the Framer.</p><p>The integration went well, and we were able to control the height for the first element and width for the second:</p><iframe src="https://cdn.embedly.com/widgets/media.html?src=%2F%2Fcoub.com%2Fembed%2Fhbjku%3Fmaxheight%3D360%26maxwidth%3D640&amp;display_name=Coub&amp;url=https%3A%2F%2Fcoub.com%2Fview%2Fhbjku&amp;image=https%3A%2F%2F3fc4ed44-3fbc-419a-97a1-a29742511391.selcdn.net%2Fcoub_storage%2Fcoub%2Fsimple%2Fcw_image%2F03f9a50abfe%2F074bc24967618aad0333b%2F1479912634_00032.jpg&amp;key=a19fcc184b9711e1b4764040d3dc5c07&amp;type=text%2Fhtml&amp;schema=coub" width="640" height="360" frameborder="0" scrolling="no"><a href="https://medium.com/media/2302e34d3719f92c3907595eac3218b4/href">https://medium.com/media/2302e34d3719f92c3907595eac3218b4/href</a></iframe><p>We took a pre-recorded training video and superimposed our interface on top of it. This is how the first approximation looked in real time:</p><iframe src="https://cdn.embedly.com/widgets/media.html?src=%2F%2Fcoub.com%2Fembed%2Fitj14%3Fmaxheight%3D360%26maxwidth%3D640&amp;display_name=Coub&amp;url=https%3A%2F%2Fcoub.com%2Fview%2Fitj14&amp;image=https%3A%2F%2F3fc4ed44-3fbc-419a-97a1-a29742511391.selcdn.net%2Fcoub_storage%2Fcoub%2Fsimple%2Fcw_image%2Ff86ab7dd67c%2Fbef6c4720c4855ac7dce5%2F1481214297_00032.jpg&amp;key=a19fcc184b9711e1b4764040d3dc5c07&amp;type=text%2Fhtml&amp;schema=coub" width="640" height="360" frameborder="0" scrolling="no"><a href="https://medium.com/media/1bbd29bab3934064e49bcb48c5b0ab78/href">https://medium.com/media/1bbd29bab3934064e49bcb48c5b0ab78/href</a></iframe><p>We showed the clients our first attempts: the principal idea with two visual elements seemed promising, and we decided to stay with it, working in more detail on different states and making the graphics more legible from a greater distance.</p><h3><strong>Next steps</strong></h3><p>We added the general counter of points, made the visual elements round so that they would visually resemble the helicopter’s panel of instruments. Then we decreased the size of the elements because it turned out that the previous size hid the image of the helicopter itself.</p><p>At this point, we received a very important comment from Andrei who told us that the helicopter couldn’t depart from the corridor for more than 0.5 m. This helped us to calculate the optimal size of the elements and the helicopter in a way that allowed to accommodate 99.9% of all cases.</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*2rx24MVAusgI3hK_tFgFKA.png" /><figcaption>Refined UI (second iteration)</figcaption></figure><p>In the previous iterations, we placed the helicopter inside the element, leaving the corridor fixed. Now, the helicopter was fixed, while the corridor moved along. This greatly increased “readability” of the elements and of interface as a whole.</p><p>And the most important innovation: when a mistake was made, we replaced the red beacon with highlighting the side of the corridor where the mistake was made. That made it even more intuitive and visible even to those looking at the screen sideways.</p><iframe src="https://cdn.embedly.com/widgets/media.html?src=%2F%2Fcoub.com%2Fembed%2Fhbl7i%3Fmaxheight%3D360%26maxwidth%3D640&amp;display_name=Coub&amp;url=https%3A%2F%2Fcoub.com%2Fview%2Fhbl7i&amp;image=https%3A%2F%2F3fc4ed44-3fbc-419a-97a1-a29742511391.selcdn.net%2Fcoub_storage%2Fcoub%2Fsimple%2Fcw_image%2F91f0d87f8a6%2Fbe874d29615c14cb908f1%2F1479914172_00032.jpg&amp;key=a19fcc184b9711e1b4764040d3dc5c07&amp;type=text%2Fhtml&amp;schema=coub" width="640" height="360" frameborder="0" scrolling="no"><a href="https://medium.com/media/35f5199dc6ceaca29054e9e5ec8e15b2/href">https://medium.com/media/35f5199dc6ceaca29054e9e5ec8e15b2/href</a></iframe><p>We added the counter of penalties for each side. The element that controlled the corridor width ended up having four of them, because this element was responsible both for the corridor width and for the helicopter’s turnaround above a square with a size of 1x1 m, where the machine could end up out of bounds on 4 sides of the square.</p><p>We elaborated on the rare instances when the helicopter may depart from the corridor boundaries by more than 0.5 m. Following some cosmetic changes, the elements now looked like this:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/700/1*SfaUk7NuACTIW2NdP6wiSg.gif" /></figure><h3><strong>That wasn’t all</strong></h3><p>In addition to the graphics that would reflect the flight through the corridor, we needed to come up with graphics conveying the execution of turns. The 360º turnaround in a set direction has to be executed within the boundaries of a landing with an area of 1x1 m, while the duration of the turnaround should not be less than 15 seconds. At the start of the turnaround, the interface launches a timer (full circle is 15 seconds) that reflects the required direction of the turn. If the crew executes turnaround too fast, it’s reflected on the screen immediately:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/700/1*z2KAySMdbNDKHjU15gMPRg.gif" /></figure><h3><strong>Homestretch</strong></h3><p>A separate stage of the event is the landing. A line with a width of 5 cm is marked on the landing pad, and the helicopter has to land on that line with special marks on its landing gear (the width of the mark is 1 cm).</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*FZy__s2I4GbLHqD8e01v4A.png" /><figcaption>Landing</figcaption></figure><p>The judges determine the marks’ position relative to the line with the help of a ruler, so this process takes some time before the results appear on screen.</p><p>To keep the audience entertained during the measuring process, we added the animated video tracking event’s execution and highlighting all the mistakes that were made.</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/700/1*Jjh4wZFEcMehMMn9przW8w.gif" /><figcaption>Flight track recorded with beacon</figcaption></figure><p>Following the measurements, we show the results on-screen:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*IWFmfThG8Q636KOdagqcNg.png" /><figcaption>Visualisation of landing precision</figcaption></figure><p>Following that, we show the team’s current position:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*M-7vNKt8enXdW9ayZ7Ylvw.png" /><figcaption>Score and rank</figcaption></figure><p>And give the summary table:</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/700/1*o_MGwwduwrWn5iUoHNz5Dw.gif" /><figcaption>Summary table</figcaption></figure><h3><strong>The result</strong></h3><p>It took us exactly 5 weeks to develop and document the first version of the interface. Each week, we demonstrated our progress and explained which decisions were made and why.</p><p>In a short period of time we were able to create the MVP that satisfied all the original requirements. Moreover, the broadcast interface now performs two important functions:</p><p>Provides tutoring for the viewers unfamiliar or poorly familiar with the event’s rules.</p><p>With the help of the interface, the teams can track their mistakes and draw the relevant conclusions for the future.</p><p>We decided that we’ll work on the interface’s final style after we develop the graphics for the competition’s other five events. There’s still plenty of work ahead :)</p><h3>Final video:</h3><iframe src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.youtube.com%2Fembed%2FxB06kEPPZoI&amp;display_name=YouTube&amp;url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DxB06kEPPZoI&amp;key=a19fcc184b9711e1b4764040d3dc5c07&amp;type=text%2Fhtml&amp;schema=youtube" width="854" height="480" frameborder="0" scrolling="no"><a href="https://medium.com/media/b2de683d0ebe9f0df7546f645f59b819/href">https://medium.com/media/b2de683d0ebe9f0df7546f645f59b819/href</a></iframe><img src="https://medium.com/_/stat?event=post.clientViewed&referrerSource=full_rss&postId=b0009d26e82d" width="1" height="1" alt=""><hr><p><a href="https://medium.com/design-bootcamp/how-we-created-an-interface-for-broadcasting-helisport-competitions-b0009d26e82d">How we created an interface for broadcasting helisport competitions</a> was originally published in <a href="https://medium.com/design-bootcamp">Bootcamp</a> on Medium, where people are continuing the conversation by highlighting and responding to this story.</p>]]></content:encoded>
