3-3. Fast Read Single Block Command

The Fast Read Single Block command is the same as the Read Single Block command that reads the data

stored in the specific single block. The data rate in the response is twice as defined in ISO/IEC 15693.

If the Option_flag (bit 7) is “1”, the transponder adds block security status information in the response. If the

Option_flag (bit 7) is “0”, the transponder returns only the data in the specified block to the reader/writer.



Request

[Request from the reader/writer to the transponder]



Response

[Response from the transponder to the reader/writer]

(1) When Error_flag set

(2) When Error_flag not set

3-4. Fast Write Single Block Command

The Fast Write Single Block command is the same as the Write Single Block command that writes the single

block data included in the request. The data rate in the response is twice as defined in ISO/IEC 15693.

The transponder performs verification after writing and returns an error code if the writing has failed.

If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write

operation starting after “t1nom (320.9 s) + a multiple of 4096/fc (302.1 s)” with total tolerance of 32/fc

(2.4 s) and latest within 20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/

writer and upon such reception still return its response (However, if an EOF is not sent within 38 ms, the

time-out occurs and the transponder can receive another command) .
