Decoding Chinese RFID Ebay Auctions

Some very basic (but very useful) notes regarding RFID products on Chinese ebay auctions for RFID readers. This includes wiegand receivers. This is mainly for the cheap RFID readers/cards/etc. found on e-bay.

  • If it says “ID” anywhere in the ad, 125Khz
  • If it says “IC” anywhere in the ad, 13.56Mhz.

The standards listed (14443A, M1Card, etc.) are used randomly even though the devices may not be compatible. It appears the fall-back is the ID/IC standard for whether your card is LF or HF. The likelihood of a dual-band reader existing on ebay is VERY VERY slim.
