The memory banks have different sizes depending on the type of ID tag, so the maximum data length
that can be used varies. Further information can be found in the data sheets of the ID tags.
EPC memory bank
The EPC memory bank stores the EPC and additional data:
Memory area Type Description
0x00 - 0x0F CRC 16 bit CRC over the content of the EPC
memory bank
0x10 - 0x1F PC Bits Protocol Control Bits
0x20 - End of memory bank EPC Electronic Product Code
0x210.0x21F XPC Extended Protocol Bits
With the operating mode "WRITE EPC", the EPC is written to the ID tag. (Ò Operating mode "WRITE
EPC”/26) The additional data is managed by the device.
Passive ID tags are powered wirelessly by the device's high-frequency alternating field. The
field strength decreases sharply with increasing distance between the device and the ID tag.
This means that less energy is available to the ID tag for long distances.
Writing data to the ID tag requires more energy than reading data. Therefore, the maximum
distance between the device and the ID tag is less when writing data than when reading data.
9.13.5 Write protecting the ID tag
The ID tags can be write-protected. When write protection is active, a password is required for writing
to the memory banks of the ID tag.
Memory bank Description
EPC EPC can be write-protected by the user with a password.
TID TID is always read-only and cannot be changed.
USER USER can be write-protected by the user with a password.
RESERVED RESERVED is always read-only and cannot be changed.
With the write protection, only the writing of data can be prevented. Reading data is always
possible regardless of write protection.
