Here is an update, now, Apple is opening up their TEE(eSE) nfc apis.

And samsung's TEE nfc api still behind application requirements.

This is a simple change that could potentially have a great impact on many people's lives who use Access Cards. Please, Samsung, we need this feature — just copy Apple!

[Adam BZH]

well, let's see when they gonna figure this out. I personaly already lost hope to them, got a cuid card sticker instead

But smartphone suppose to be an integrated devices, which integrate multiple function to a single device. Not doing the opposite which disable a function on purpse then force user get extra hardware or find other ways around, why not get another brand then?

Adam, I bought some NFC stickers to clone my cards (NFC Ntag 213 - 13.56MHz), but they didn't work for cloning the card I have. In NFC Tools Pro, it says Mifare Classic 1K, and the one I bought is Mifare Ultralight. Also, the length of the serial number is larger for the Ultralight I bought. Do you know what type of NFC sticker I should buy?

[Adam BZH]

no you are using the wrong thing

before you start, make sure you are legally allowed to own card and access what the card get you in to, lol

first, make sure your card is actually readable form your phone, becuse some old system use 125khz instead of 13.46mhz

then, buy cards by search keyword "cuid card" on something like aliexpress, usually very cheap.

then, get app called "MIFARE Classic Tool" to clone your own card

[Edemir Santos]

Yes, I want to access places where I have permission, my home and my workplace, but the card is very large, and I always have to carry one or the other. This way, the sticker could replace them. I found this one on Aliexpress https://pt.aliexpress.com/item/1005006860880949.html. Is it the right one for this purpose?

[Adam BZH]

yeah, that should be the right type

also, you may want try dump your card first, some M1 card have non-default keys which requires crack before dump and clone

if your card is encrypted(protected by keys), you may want a usb to PN532 reader module and the software to crack it

[Adam BZH]

btw, if you buy sticker,  keep in mind followings

they are weak on metal surfaces

if it's too small it can be hard to read

do not put them next to each other, most reader won't work when there is a signal collision

[Edemir Santos]

I dumped the keys using MCT, but there's no Sector 0. Also, in the other sectors, the first three lines are all 0000000000, and the fourth line is different but the same across all sectors.

I wonder if I buy one of these CUID stickers and change to the same UID, will it work?
