The most commonly used types of chips (IC) in HF technology

The ranges of the HF frequencies go from 3 to 30 MHz. Most RFID HF systems work with 13.56 MHz, with reading ranges between 10cm and 1m. Interferences moderately affect HF systems.

HF systems are commonly used for ticketing, payments and data transfer applications.

There are a few standards for HF RFID: ISO 15693 is the standard for object traceability; ECMA-340 and ISO / IEC 18092 are for the NFC (Near Field communication), a technology with short reading ratio used for change of data between devices. The MIFARE standards are ISO / IEC 14443 A and ISO / IEC 14443, which is used in smart cards, and JIS X 6319-4 for FeliCa which is normally used in cards with payment systems.
