Claim:
A transponder comprising: a transmitting and receiving device configured to receive commands and transmitting data; a command processor configured to execute the commands; a programming device configured to change a memory content; and a data memory having a first memory area and a second memory area, the first memory area configured to have a first value that indicates that a predefined or no data stream should be transmitted or a second value that indicates at least one part of a content of the second memory area should be transmitted; wherein, when the first memory area has the first value, a content of both the first and second memory areas is changeable; wherein the transponder is capable of being communicatively connected to a base station through a wireless medium; wherein the programming device is further configured to examine the first memory area in response to receiving a read command for the content of the second memory area from the base station, and: in response to determining that the first memory area has the first value, cause the transponder to transmit a predefined or no data stream instead of a memory content of the second memory area back to the base station by using the transmitting and receiving device, the predefined data stream including no portion of the content of the second memory area; and in response to determining that the first memory area has the second value, cause the transponder to transmit at least one part of the content of the second memory area to the base station by using the transmitting and receiving device.
