Barcode reader and accessory for the barcode reader
First Claim
1. A power/data cable accessory for providing operating power to a hand-held barcode reader and providing decoded data of a barcode received from the barcode reader to a host computer, to which the power/data cable accessory is not physically connected, via a wireless interface, the power/data cable accessory comprising:
- a first connector for connecting to the barcode reader;
a second connector for connecting to a power source;
an elongated and flexible cable between the first connector and the second connector;
an interface system coupled between the first connector and the second connector, the interface system comprising;
a power circuit drawing power from the second connector and providing operating power to both the barcode reader, via the first connector, and the interface system;
a processor;
memory;
a first connector interface receiving the decoded data from the barcode reader via the first connector; and
the wireless interface for providing the decoded data from the interface system to the host computer, wherein the host computer is not the power source to which the second connector is connected.

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.

11. A power/data cable accessory for providing operating power to a hand-held barcode reader, comprising:
-
a wireless interface for establishing a wireless communication link with a host computer which is separated from the power/data cable accessory, receiving information from the host computer, and transmitting information to the host computer; a first connector for connecting to the barcode reader; a second connector for connecting to a power source; an elongated and flexible cable between the first connector and the second connector; and a power circuit drawing power from the second connector and providing operating power to the barcode reader, via the first connector, the wireless interface, and an interface system that is coupled between the first connector and the second connector; the interface system being configured to; pass all the information received from the host computer via the wireless communication link to the barcode reader via the first connector; when operating in a pass-through mode, pass information received from the barcode reader via the first connector to the host computer via the wireless communication link; and when operating in a command mode, process authentication information received from the barcode reader via the first connector and return to the barcode reader results of processing the authentication information. - View Dependent Claims (12, 13, 14, 15)

16. A power/data cable accessory for providing operating power to a hand-held barcode reader, comprising:
-
a first connector for connecting to the barcode reader; a second connector for connecting to a power source; an elongated and flexible cable between the first connector and the second connector; an interface system coupled between the first connector and the second connector, the interface system comprising; a power circuit drawing power from the second connector and providing operating power to both the barcode reader and the interface system; a wireless interface for communicating with a host computer; an authentication coprocessor; and a processor configured to; pass information received from the host computer, via a wireless connection formed with the host computer using the wireless interface, to the barcode reader; provide for the authentication coprocessor to process authentication information received from the barcode reader, generate authentication results, and return the authentication results to the barcode reader via the first connector thereby enabling authentication of the barcode reader to the host computer; and following authentication of the barcode reader to the host computer, pass decoded barcode data received from the barcode reader via the first connector to the host computer via the wireless connection. - View Dependent Claims (17, 18, 19)
