Abstract

See full text

Techniques described herein enable wireless payment reader to transition between lower-power and higher-power states while still performing cryptographic operations for securing payment data without undue latency caused by the transition between sleep and awake power states. For instance, a wireless payment reader may store information associated with cryptographic operations performed by the wireless payment reader in persistent memory of the wireless payment reader so that this information may be retained when the wireless payment reader enters a low-power, sleep state. Thus, when the wireless payment reader awakens from the low-power state, the wireless payment reader may read the cryptographic information from the local persistent memory rather than needing to request this information from a payment service.
