Cards is a mobile wallet app that allows users to store all their cards, tickets, passes, and keys in one place. The app is designed to be safer, faster, and more useful than carrying a physical wallet. With Cards, users can perform a variety of actions such as paying, catching a bus, opening doors, getting loyalty offers, identifying themselves to officials, and getting into shows, among other things. The app allows users to perform card-specific actions directly from their favorite cards, such as ordering a pizza from Pizza Card, flight tickets from Airline Card, and tracking parcels from Courier Card.

Cards can store a wide range of cards, including loyalty cards, payment cards (credit/debit/ATM), transport cards (bus/train/metro), identity cards (driver's license/student/ID), tickets (shows/movies), key cards (work/car/home entrance), and more. Users can load any card to their phone, send cards by tapping their phone on terminals or other devices using NFC wireless technology, or send cards by presenting barcodes. The app also offers Cards Apps, which allows users to perform tasks from within Cards without downloading bloated and unfamiliar apps. Quick Card allows users to instantly access any card, and they can get notifications from their cards.

Cards takes privacy and security seriously and uses the highest available security standards and technology. The app is completely encrypted, and users can remotely lock their wallet. They can unlock Cards with their fingerprint or PIN code, and transactions are authenticated and signed. For developers, Cards offers free and easy-to-use SDKs (Java, C#, NodeJS, C++, Python) and APIs to connect their business, app, website, or NFC reader.
