i did carding for fun but i quit
it is simple reader that gives you data and you write it on blank card and it can work (we leave our backpacks on the desk at work, so easy)
for ex. i told peoples card numbers and exp. date and they scare or tell them that is on me and pay with their stolen cards later thank them for dinner, they said you pay and i insist open the bank app you pay not me, fun with them like you get older or go to hospital for dementia, just for fun with close friends money is not important in our friendship culture
but
osmosis vanderwaal is right, carding is a scam
if someone steal hundreds of data maybe sell it but that is nonsense because if i got 100 card data i can use it in a week and get rich
