HF Technology

HF RFID technology is working at 13.6 MHz frequency. High frequency 13.56 MHz technology is mature and was one of the first forms of RFID to be successfully commercialized especially for access control and contactless payment applications. Tags and readers in 13.56 MHz systems communicate by coupling in the electromagnetic field. The frequency, and electromagnetic communication, provides excellent resistance to common sources of interference found in commercial and industrial environments. The well-known drawback of 13.56 MHz technology is its limited range, which tops out at about 1 meter. Reading speed for 13.56 MHz tags is also relatively slow compared to UHF technology.

There are several widely used protocols and standards for 13.56 MHz technology. The best-known standard is ISO 15693, which is often used as the basis for presenting 13.56 MHz technology characteristics.. ISO 15963 was developed as a standard for contactless cards. There are many interoperable ISO 15693 tag and reader products, which are also used for other applications, including commercial laundry tracking, library book management, file tracking and sample identification. ISO 14443 is another leading 13.56 MHz standard. It was created for contactless fare collection and other electronic payment transactions, and is widely used in public transportation systems. Because 13.56 MHz was one of the first RFID technologies to be standardized and gain wide vendor support, it was tried for numerous applications. However, the range limitations of 13.56 MHz technology didn’t support efficient case and pallet handling operations. The shortcomings specific to 13.56 MHz technology for identifying goods in distribution and supply chain operations.
