JCB and Keychain Implement Offline Payments using NFC

Japanese payments network JCB recently showed its machine-to-machine payments infrastructure that enables merchants to accept near-field communication (NFC) payments, even when the customer and merchant are both offline.

JCB’s machine-to-machine payments infrastructure uses NFC, blockchain and self-sovereign identity technology to launch payments processing that ties into Internet of Things (IoT)-equipped devices, smartphones, wearables and other devices.

The system also leverages Keychain’s blockchain and self-sovereign identity technology to address the challenges associated with operating through network outages and cyberattacks.
