Active 2.45Ghz RFID Keychain Tag for Access Control

The HC-PA11 keychain can have multiple operating frequencies. 2.4GHz can be identified from a long distance, making it more secure. The tag comes with a 125k low-frequency activation function, which needs to be triggered to be recognized by the 125Khz antenna. Mini appearance, generous and beautiful, small and exquisite, convenient to carry, there are 4 colors to choose from, can also help customers to print LOGO, add SOS function according to customer needs. Tags are widely used in parking lot, employee attendance, personnel positioning, vehicle management and so on.

About RFID

Automatic identification technology that uses radio frequency signals to achieve

non-contact information transmission through space coupling (alternating magnetic

field or electromagnetic field), and achieves the identification purpose through the

information. Conventional use in regional personnel positioning has great advantages.

 Calculation

Method

Checksum calculation: In sum of all hexadecimal values, the end byte is 0

23 + 30 + 30 + 30 + 30 + 30 + 30 + 30 + 31 + 31 + 35 + 30 + 34 + 31 + 38 + 30 + 38 + 30 + 38 + 30 + 39 + 30 + 30 + 32 + 32 + 30 + 34 + 36 + 35 + 31 + 38 + 45 + 39 + 39 + 39 + 30 + 30 + 30 + 30 + 7D = 800 (combined value end byte is 0)
