Video link; https://sharefiles.eu/direct/kxl2ovCcSjQYV0Q6wadOQiRH DIEZ Proxy Card by OtherPay is a secure travel payments app created for people spending outside their home country. DIEZ means “10” in Spanish and reflects Lionel Messi’s iconic playing number, bringing a globally recognised brand identity to a practical travel payments solution. The app allows users to link their existing debit, credit, prepaid, charge and other eligible payment cards into one protected mobile experience, then choose which card they want to use before making a transaction. Built for travel, DIEZ helps customers reduce the risk of card misuse when shopping overseas, paying online, using ATMs or making in-store purchases. Instead of exposing multiple cards while travelling, users can manage their linked cards through the DIEZ app and use the DIEZ Proxy Card as a controlled payment access point. The app is powered by OtherPay’s intent-based payment security architecture. Before a transaction can proceed, the user must actively confirm their intent through the app, helping ensure that card activity is deliberate and authorised. This approach is designed to protect users by making verified intent a prerequisite to payment execution, rather than relying only on traditional card credentials. Key features include: • Link multiple eligible payment cards into one travel-focused app • Select a preferred source of funds before use • Add and verify cards through a secure card validation process • Use the DIEZ Proxy Card for in-store, online and ATM transactions where supported • Confirm payment intent before execution • Protect linked cards by reducing unnecessary exposure while travelling • View and manage linked cards from the mobile app • Lock or control card access from within the app • Use biometric authentication and secure device-based activation where available • Access a simple digital wallet-style interface designed for international travellers DIEZ is designed to give travellers more control over how their existing cards are used abroad. Whether paying at a merchant, shopping online, accessing cash or managing multiple cards during a trip, the app provides a single, secure layer between the traveller and their underlying funding sources. The DIEZ Proxy Card and app are intended to support safer, more convenient and more controlled travel spending by combining familiar card payment functionality with OtherPay’s secure execution and card-linking technology, supported by the international appeal of the Messi DIEZ brand.
