Mifare 1k UID changeable card EU sale

Hi everyone,
I think i may be able to sell the chinese Mifare 1k cards with editable UID in europe for 3 € each tag.
Shipping would cost 1€ for standard EU non tracked shipping, and 5€ for tracked shipping. I don't have the stock yet, but it will arrive soon. I just need to know if there's a sorto of ask for this.
I wil accept paypal and maybe bitcoin.
Just let me know if you are interested, and if there's enough, i will get them, post pictures and then start selling.

Those card are 1st gen (need special commands to write block0) or 2nd gen (no need for special commands to write block0)?

While it's not stated clear by the seller, i believe that the card are 'gen 1' because are still the ones defined as 'backdoored', however i asked the seller for more details about that.

@MilkThief: the difference is basically that with the first generatin tag you can write the block 0 (the uid) only with dedicated commands, like the proxmark have while in most case you can't for example using your phone or a standard reader.

Those special commands can be ONLY sent if the device you are using is able to send partial bytes command (like the 25 or 52 using mifare tags protocol). If your device does not support partial bytes (ex. ALL mobile phones do not support that and it is IMPOSSIBLE to be implemented because nfc chip firmware is encrypted) you cannot write sector0block0 of 1st gen changeable UID mifare cards. Those info are extended explained in the MCT thread.

Ok, so, do you confirm those card block0 are writable with the the "backdoor" on PM3 (from r588) and with the libnfc "write unlocked" command?

Ok, keep me in list and I'll decide after your tests.
I have no nexus or android compatible, so I'll use a PM3 or ACR122 only...
Thank you.
