c)
Reader’s response (successful write)
If the write operation has been successful, the reader will send an end of data packet with the success byte set
to 1 (one). On the other hand, if the operation has failed, the reader may send the tag ID and an end of data
packet with the success byte set to 0 (zero).
The following is an example of the reader’s response:
DE 00 02 81 01,
where
-
DE 00 02 81 01: end of data, where 00 02 – length, 81 – command ID, 01 – success status (01 means
success)
d)
Reader’s response (write failure)
If the reader cannot write the tag data, the reader’s response will be the following:
DE 00 02 81 00,
where:
-
DE 00 02 81 00: end of data, where 00 02 – length, 81 – command ID, 00 – success status (01 means
failure)
Please note that most Mifare 1K cards have pages that are read-only. The developer should not try to modify
those fields as the results are unpredictable (e.g. the reader may report a success even though the write
operation failed). Please refer to the used RFID tag manufacturer specification for more details.
