Barcode reader and accessory for the barcode reader

摘要

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.

1. An accessory for a barcode reader for providing operating power to the barcode reader and providing decoded data of a barcode received from the barcode reader to a host computer, the accessory comprising:
a first power/data connector for connecting to the barcode reader; and a second power/data connector for connecting to a power source and providing operating power to both the barcode reader, via the first power/data connector, and an interface system, the interface system including:
a processor;memory;a first power/data interface for receiving the decoded data from the barcode reader via the first power/data connectors;a wireless interface for providing the decoded data to the host computer, wherein the host computer is not the power source to which the second power/data connector is connected; andan authentication system;wherein the interface system is configured to operate in both a command mode and a pass through mode;wherein in the command mode, the processor is configured to:
receive, and provide to the authentication system for processing, authentication information received from the barcode reader via the first power/data connector, andreturn to the barcode reader, via the first power/data connector, the results of processing the authentication information by the authentication system; andwherein in the pass through mode, the processor is configured to pass information received from the barcode reader to the host computer via the wireless interface.
