摘要:
Systems, methods, and articles of manufacture for secured account provisioning and payments using near-field communication (NFC) enabled devices are provided. The system may receive an encrypted account provisioning request comprising a provisioning account and a device fingerprint; decrypt the encrypted account provisioning request with a server root key; retrieve a limited use payment credential (LUPC) based on the provisioning account; generate an ENC key, a MAC key, and a DEK key based on the device fingerprint and the server root key; and encrypt the LUPC using the ENC key, the MAC key, and the DEK key to generate an encrypted account payload.
