Set UID for MiFare card.

Hi there,

How can I set a different UID for the following MIFARE card?
What command should I use?

Thank you

Re: Set UID for MiFare card.

If this is a MiFare card, you will NOT be able to set the UID. If it is a magic card, you can.

To set the UID on the magic card, use the command "hf mf csetuid". See below.

[usb] pm3 --> hf mf csetuid --help

Set UID, ATQA, and SAK for magic gen1a card

usage:
    hf mf csetuid [-hw] [-u <hex>] [-a <hex>] [-s <hex>]

options:
    -h, --help                     This help
    -w, --wipe                     wipes card with backdoor cmd`
    -u, --uid <hex>                UID, 4/7 hex bytes
    -a, --atqa <hex>               ATQA, 2 hex bytes
    -s, --sak <hex>                SAK, 1 hex byte

examples/notes:
    hf mf csetuid -u 01020304
    hf mf csetuid -w -u 01020304 --atqa 0004 --sak 08

Re: Set UID for MiFare card.

Thank you for your response.
How can I find if this is a magic card or not magic card?
