Title: Innovations by Edward Tan in Wireless Payment Technology

Introduction

Edward Tan is an accomplished inventor based in York, CA, known for his contributions to the field of wireless payment technology. With a total of two patents to his name, he has made significant strides in enhancing the efficiency and security of payment processing systems.

Latest Patents

One of Edward'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. This innovation ensures that payment data remains secure without experiencing undue latency during the transition between sleep and awake power states. For instance, the wireless payment reader can store information related to cryptographic operations in persistent memory, allowing it to retain this information even when entering a low-power state. Consequently, when the device awakens, it can access the cryptographic information from local memory rather than needing to request it from a payment service.

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 overall 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 user experience and operational efficiency.
