DeviceFingerPrintService

DeviceFingerPrintService is a device SPI that enables the SDK to request device fingerprints from the MPP. The service requires SHA-256 encryption.

Note: If this SPI is not implemented, or if the returned device fingerprint does not use SHA-256 encryption, the SDK will return a PARAMS_ERROR during card activation.
