RFID frequency in INCH

Do you use a RFID card to open a garage door ... and would you like to use it at the INCH charging station?


RFID tags and readers have to be tuned to the same frequency in order to communicate. There are several different frequencies an RFID system can use.  Generally, the most common are

  • Low frequency, or LF, (125 – 134 kHz)

  • High frequency, or HF, (13.56 MHz)

  • Ultra-high frequency, or UHF, (433, and 860-960 MHz)


RFID cards operate at different frequencies:

  • 125 kHz is used for a variety of simple approaches

  • 13.56 kHz is the standard for electromobility. All chargers in the EU and other continents use it. This can also make roaming work.

RFID specification in INCH:
• Supports I2C, SPI and HSU (High speed UART)
• 5 to 7 cm reading distance

Supported cards:
• Mifare 1k, 4k, Ultralight and DesFire cards
• ISO/IEC 14443-4 cards (CD97BX, CD light, Desfire, PSCN072(SMX))
• Innovision Jewel cards (IRT5001)
• FeliCa cards (RCS_860 and RCS_854)
