A fast block write command includes providing an RFID tag having a memory, and using a stored address pointer to point to a known address in the memory, wherein the stored address pointer points to a starting address at a known safe block in the memory. The method is performed without an intermediate buffer. The received data is written to the known safe block and a cyclic redundancy check is computed on the received data. If the cyclic redundancy check matches, the received data is retained and the stored address pointer is updated. If the cyclic redundancy check does not match, the stored address pointer is kept for a future write operation. Further block writes can be disallowed after an initial successful block write.
