I can try…
Mifare CLASSIC vs. Mifare NTAG
Keeping it bare basics for you
The Mifare CLASSIC Magic 1k Is an early HF technology, commonly used in many older security systems, but still readily available in alot of “Chinese” products.
The S50 chip was cracked and allows us to write our own 4byte NUID. This is the Chip we use in our implants ( xM1 , FlexM1 gen1a and gen 2, FlexMT…)and with software / apps we can read and write to them.
The fix that followed included a 7byte UID which means if a newer system requires the full 7Bytes we are S.O.L
The use of the Term Mifare is another story mostly unrelated to your question.
A Much more comprehensive explanation can be found in Amals Info Post
If you need further clarification just ask and I can try to expand further
Rather than the Mifare Classic that we can use on Mifare Classic systems and change the NUID, The Magic Ntag card can emulate a few different types of cards ( BUT NOT Mifare CLASSIC )
It can obviously emulate:
- MIFARE NTAG 213, 215 (215 is used for Amiibo), 216 ( 216 is the same as in the NExT etc )
These are 100% emulated,
These are limited emulated ( counter and tearing emulation are not 1:1 with original chipsets.)
ALSO - Mifare NTAG®
210
212
I2C 1K
I2C 2K ( I2C 2K is the same as in thexSIID )
I2C 1K Plus
12C 2K Plus
And the MIFARE Ultralight which is often confused with the MIFARE Classic
- MIFARE Ultralight
EV1 48k
EV1 128k
So the MIFARE Magic NTAG is capable of emulating a lot more products than the CLASSIC so it is a potentially a great option for a lot of situations.
Although the NTAG MIFARE Ultralight EV1 emulation is IN THEORY 100% compatible with all MIFARE readers, writers and software, I am not 100% sure this will include the MIFARE Classic readers, writers and software; Personally I think it will come down to the specific reader, But I stand to be corrected on that one ( and anything else I have mentioned above for that matter )
Anyway
If / when I get the FlexMN, That is something I will test, unless somebody already has.
If you want, you can grab a test card from KSEC
I hope that goes some way to clarifying for you, sorry it was longer than I planned.
But again if you need more explanation, just ask
