normally in order to write you need a magic gen 4 card and with the nfc magic app after you verify your magic card you can then write to it by choosing a saved card, but after you read the mifare you will just be able to save it or emulate it, you need the magic card to see the write option
If I buy a T5577 tag, will I be able to use it instead of a magic card and clone my card ? Or do I need to choose only gen 2-4 cards instead of rewritable cards ?
it depends on the frequency of the card, a T5577 card is for low frequency cards(125kHz) however gen2-4 are for high frequency cards(13.56MHz) and depending on the type you will need either a gen2 or a gen4. You can find out if you have a low or high frequency by checking the original card with a flipperzero or a proxmark
@@TechSecurityTools I already have a card 13.56 mhz (classic 1k) Would a rewritable 13.56 MHz card be suitable instead of gen 2 or gen 4 or is a gen 4 card required
@@TechSecurityTools I ordered a CUID card. It is not UID, so will it still work or I don't understand what is the difference between CUID and UID? You said it would work as UID and I already ordered CUID, I hope it works. Thanks for support
@@MuhammetGunalp CUID should work. The difference between a CUID and UID is that there are two types of Mifare Classic 1K. The normal one that has a 4-byte UID and a second one that has a 7-byte UID. With the UID magic gen1a card you can only do the normal Mifare Classic 1K (4-byte UID) however the CUID can do both. Since you have a CUID you should be fine.
can you tell me why i can read my NFC Fob, but i don't have the option to Write after is saves the info? it is a Mifare DESFire EV2 type 4

@@MuhammetGunalpif you have a mifare classic 1K all you need is a mifare rewritable uid(gen 1a) that's all. The gen 2 or gen 4 isn't required
