Abstract
A barcode reader and an accessory are disclosed. The accessory may include an interface system and a wireless and/or wired interface for communication with a host computer such that the barcode reader may communicate with the host computer via the accessory. The interface system includes an authentication coprocessor such that the barcode reader may establish mutual authentication with the host computer using the authentication coprocessor of the interface system. The barcode reader may send a request for an accessory identifier, and the accessory may then query the authentication coprocessor for the accessory identifier and provide the accessory identifier to the barcode reader. The barcode reader may send an authentication challenge to the accessory, and the accessory may then present the authentication challenge to the authentication coprocessor to obtain an authentication response, and provide the authentication response to the barcode reader.
