Keycard is a new credit-card sized hardware wallet featuring near-field communication (NFC) to authorize cryptocurrency transactions. At launch, it features integration with combined private messenger/wallet/DeFi browser, Status App, although further integrations are planned.
The Keycard team has also released an open application programming interface (API) and software development kits (SDK) for Android, iOS and Go, so that developers can build Keycard functionality into any app requiring authorization or other user authentication.
