High Frequency RFID Chip
The common frequency is the 13.56MHz ISM band. The RFID sticker tag in this band is still passive, and it also uses inductive coupling for energy supply and data transmission.
The biggest application of RFID chips in this frequency band is the contactless smart cards we are familiar with.
Compared with low frequency, its transmission speed is faster, usually above 100kbps, and it can be identified by multiple tags (each international standard has a mature anti-collision mechanism). The system in this frequency band benefits from the application and popularity of contactless smart cards. The system is also relatively mature, and the price of reading and writing equipment is relatively low.
High-frequency RFID chip products are the most abundant, with storage capacity from 128 bits to more than 8K bytes, and can support high security features, from the simplest write lock, to stream encryption, and even encryption coprocessors are integrated . Generally used in identity recognition, library management, product management, etc. RFID applications that require high security, this band is currently the only option.
Please select the corresponding chip according to the system you are using. If you are not sure which one to choose, please contact us.
