Mifare is not NFC compliant… it is not one of the NFC Forum’s 5 NFC “types”. The company behind it, NXP, has created a bullshit workaround that only works if your phone has an NFC reader chip from NXP inside… but it’s still not standards compliant. There are other more long winded posts on the forum about this…
Both chips are 13.56MHz and ISO14443A compliant, but they have dramatically different memory structures and features. The xNT is based on the NTAG216 chip which is also NFC Type 2 compliant, and the xM1 + is based on a Chinese clone of a Mifare Classic 1k chip, which is not NFC compliant.
Many legacy systems still use the Mifare Classic, so the xM1 + might be useful for people who want to clone their Mifare Classic 1K cards to an implant. If you do not have a specific need for the xM1 + I would n…
Mifare also sucks as a term.
HF is “high frequency” and means 13.56MHz
LF is “low frequency” and means 125kHz - 134kHz and for all intents and purposes they are the same. For example, the Halo reader can read both 125kHz and 134kHz tags with the same antenna because basically they are so close they are the same when it comes to coupling. The major differences between any RFID tags is the protocols, memory structures, data encodings, and command sets.
Mifare is a marketing term that has been bastardized so badly it’s alm…
