3-5. 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.

3-6. 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 + a multiple of 4096/fc (302.1 µs)> with total tolerance of ±32/fc (2.4 µs) 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 <t1nom : typical 320.9 µs> (However, if an EOF is not sent within 38 ms, the
time-out occurs and the transponder can receive another command) .
