Software pin entry

This invention outlines a system where a mobile phone connects to a card reader to process payments. To protect a customer's PIN when they enter it on the phone's screen, the system prevents the screen from showing the input and uses a secure server to manage the entry process. The communication between the phone and the card reader is also encrypted. The claims specifically detail a method where the mobile device receives an identification code from the card reader to establish this secure connection.

Why it matters: Mobile device security features like secure enclaves and robust cloud infrastructure have matured significantly since 2013, making secure software PIN entry more feasible and reliable. This could simplify compliance with evolving payment security standards.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
