What frequency do contactless ic cards use?

     The contactless IC card, also known as the radio frequency card, is composed of an IC chip and an induction antenna and is encapsulated in a standard PVC card. It successfully combines radio frequency identification technology and IC card technology, ending the problem of passive (no power in the card) and contact-free, which is a major breakthrough in the field of electronic devices.

     There are multiple frequencies available for contactless ic cards. Which frequency chip to use for contactless ic cards depends on the customer's card reader configuration. There are the following commonly used chips:

     (1) Low frequency ID card
     The low-frequency ID card frequency is 125KHZ. The data can be read and written and there is a unique ID internal code. The induction distance is 5-10cm and can be used for 10 years. It can read data 100,000 times and is easy to use ID card operation.

     (2) High frequency IC card
     The high-frequency IC card frequency is 13.56MHZ. The data can be read and written and the storage capacity is 1024 bytes. The protocol is ISO14443A and the induction distance is 3-5cm and can be used for 10 years. It can read and write data 100,000 times and has strong security, good stability, and become a multi-purpose card.

     (3) Ultrahigh frequency IC card
     The Ultrahigh frequency IC card frequency is 915MHZ, and the card reading distance can reach 3-10M, which can meet the data reading at a longer distance.
