1. ISO 18000-6C/EPC C1G2 , ISO 18000-6B, and GB/T29768-2013(optional).
2. The maximum output of the port is 33dBm, and the power can be set according to the needs. It can cope with a very intensive use environment. The multi-tag recognition algorithm is the strongest in the industry. It can recognize more than 600 tags per second.
3. Able to work with fixed frequency or frequency hopping.
4. Support tag data filtering, support anti-collision protocol, support multi-tag identification.
5. Full frequency band, high power, high sensitivity, accurate power, free configuration to get the best performance.
