I want to gert started with NFC immplants. The implant is supposed to emulate my StudentID card. Which chip should I choose, to be able to copy the ID of the card and unlock the door. Which reader do I need to read/write
The reader at the door:
Nope, the Next wouldn’t work. Take a look at the xM1 or flexM1 gen 2. How many bytes does the UID have? Is it a 1k or 4k? You could also try reading it with the “Mifare Classic tool” app.
No the uid is not changeable on a NExT and its a different chip (NTAG216) you seem to need a Mifare classic.
4 bytes (8 characters) is good news. If you can get a magic mifar (gen 2 if you want to write with your phone) test card you can test it out befor getting an implant.
The “4kB” at the top tells you that it is a 4k card.
Now, if your card is 1k that is excelent. If it’s a 4k, things become a little more complex. The xM1 and flexM1 are only 1k, but if just the first few sectors of the card are written than that shouldn’t be a problem.
I would suggest you purchase a magic Mifare Classic 1k gen2 card from KSEC (if you are from Europe) and test it out.
Ok, so it’s a 1k. That should make things a lot easier.
I think KSEC also sells to the US.
Some things to keep in mind:
there are 2 kinds of “magic” Mifare classic compatible implants, gen 1 and gen 2
– gen1 can be written with a writer that sends magic commands; they are harder to brick, but can be rejected by some readers that check if the card accepts magic commands
– gen2 can be written with a smartphone, and can’t be recognized as clones, but are a little easier to brick if you write an invalid sector 0
x series implants (little glass capsules implanted with a needle) usually don’t have stellar range with conventional readers, might be good to look at flex implants (if you are into that)
About the iRobot implant: I think it probably would, but don’t take my word for it. Do some more research. Also, I have no experience with iRobot implants. In any case try it with a card first before implanting anything
