Abstract
A card reader of a terminal is cryptographically verified upon initialization, power up, connection, or start of day processing of the terminal. A cryptographic and signed token is provided from and verified by an Encrypted Personal Identification Number (PIN) pad (EPP) of the terminal. Each time the reader initializes, the token is verified by the EPP and a new token is generated and provided to the reader for use during a next initialization cycle of the reader. If the reader lacks a token when the EPP has record that is should have the token, the reader is not authorized to perform card transactions for the terminal. If a token provided by the reader during an initialization cycle is not verified, the reader is not authorized to perform card transactions for the terminal.
