Chapter 4 How to Read RF Tags

An example of reading an RF tag using the UR21-MR-01 and UR-21-MS-01 is given below.
POS processing at clothing shop
(1) Put the RF tag close to the antenna to allow the scanner to read the information from the tag.
Antenna
For its reading range, see Appendix 1.
Check the operation of the scanner using actually used RF tags.
(2) If the data has been read successfully, it will be sent to the computer.
Note:
(1) RF tags are read using radio waves. Reading performance may be lower if there are any metal objects (other than the dedicated
stay) or equipment using radio waves (mobile phones, amateur radio stations, microwaves, etc.).
Keep it as far away from any metal objects or equipment using radio waves. Before installing the antenna, check for such
problems.
(2) The reading range is based on the center of the antenna.
(3) If another RFID device is used nearby, RF tags may be difficult to read or they could be read at all.
(4) While the scanner reads a RF tag, it should be kept parallel to the antenna where possible. If not, it may be read incorrectly or
could not be read at all.
(5) Some RF tags may be difficult to read due to the deviation of the resonance frequency depending on the material to which they
are attached.
Select RF tags with a slight frequency deviation and check the operation of the scanner using such tags.
(6) Do NOT put any heavy object on the antenna.
