The ST25 tags and dynamic tags use the 13.56 MHz HF band. They are compliant with ISO / IEC 14443A or B  and ISO  / IEC 15693 and NFC forum standards and offer a range of EEPROM memory sizes from 512 bits to 64-Kbits.

The ST25 readers add also the 840-960 MHz UHF band and , ISO18092, ISO18000, ISO29143 FeliCa, NFC Forum,  EMVCo & PBOC compliances with very high bit rate and up to 1.4W output power.
