Abstract
A system and method is described for the touchless entry of a personal identification number (PIN) at a self-service terminal such as an automated teller machine (ATM). A mobile device includes a PIN entry application. The self-service terminal includes a wireless interface for communicating wirelessly with the PIN entry application in the mobile device. A communication channel is established between a particular customer's mobile device and the self-service terminal. The PIN entry application verifies a public key for the self-service terminal at the mobile device. The customer's PIN is encrypted by the PIN entry application at the mobile device using either an ephemeral symmetric encryption key or a one-time RSA PIN transport public key. The encrypted PIN is transmitted to an encryption processor at the self-service terminal. The encryption processor decrypts the PIN using the appropriate encryption key.
