6.3.3.7. READER_RD_WR_USER_AREA
This Escape command is used to access the user data area in the reader. The user area is
located in the non-volatile memory of the reader and hence data will be retained even after
power cycle.
Note:
Frequent writes should be avoided (The non-volatile memory supports only 100K writing
cycles).
A maximum of 249 bytes can be read and written. The sector can be read and written only
as a whole.
If complete data (249 bytes) is not given during write operation then random data will be
padded to the given data and then written. If you want to modify only part of the data, read
the entire 249 bytes, modify the data you want to change and then write it back to the
reader.
