Arduino RFID(NFC) help

[cHaTrAp]

Hi, I know i know there other fourms for that. But they are pretty shit takes them for ever to respond.

Let's start over hi, so i bought an arduino because i wanted to learn more about rfid and nfc.

I am trying to copy dumbfile from a card to a nother one but i can't or more like i don't know how. I tried many thins but i don't seem to get it to work.

Right now i am stuck with hex code.

 

I don't know what to do next, some guy on fourm said that i have to put the sectors in to the datablock. But it ends with 0x(). Any idea what i am supposed to do? thanks

arduino uno, rfid-rc522. I used to do it on my samsung s7 with Mifare classic tool app. But i got iPhone so i can't anymore.

I have the keys.

 

if it's that tricky, i would appreciate if you pointed me in the right direction.

well arduino uno doesnt have enough ram for doing ram(only 2 kilobytes!) so if you want to do so with a uno you can buy a eeprom copy data to that (use it as a cache) and copy that to new card
