Latest Patents

One of Hayford Peprah's latest patents focuses on decreasing cryptographic-operation latency on payment readers. The techniques described enable wireless payment readers to transition between lower-power and higher-power states while performing cryptographic operations for securing payment data. This innovation allows the payment reader to store information related to cryptographic operations in persistent memory, ensuring that the information is retained even when the device enters a low-power sleep state. Consequently, when the device awakens, it can access the cryptographic information from local memory, eliminating the need to request it from a payment service, thus reducing latency.

Another notable patent involves waking payment readers using point-of-sale (POS) devices. This patent outlines techniques for wireless payment readers to transition between multiple power states, including low-power states that extend battery life. The POS application can trigger the wireless payment reader to switch from a lower-power state to a higher-power state when a payment is to be processed, enhancing the overall user experience.
