MTools Mark Byte And Read Credit with NFC and PCR532 BLE Reader

[@creativevillan1443]

NFC card's are used to play games in our country, like pre a paid card. each time we must have to pay a huge amount and that amount recharge on that NFC card, each swipe take the cash and keep the balance on it ! You can use until its -"0".
How to bypass those payments and manipulate those machines for having more Chance to play games,pliz make a video humble request 🙂

I would try to see if the balance is stored on the card or server side. If it is on the card I would try setting in to -1 in case it only checks for 0

When i do it with mine i can never find the cridits in the dump.
I convert from decimal to hexadecimal but i can't find the hexadecimal value i got from the converter in the dump

You can do a comparison of 2 dumps with different credit.

@@mtoolstec Yep, that's what I did but practically every value changes

[@mtoolstec]

You need to exclude the useless bytes, and then filter to get the valid bytes.

Hello do you speak French?

[@laxativz]

how did you know which block in which sector the money byte was in

[@mtoolstec]

Get the different dump files with Proxmark3X, iCopy-XS, or PN532, then compare the block that changes. Also, you need to convert the credit to HEX value to do the comparison.

@@mtoolstec I oh i see, so you have to use the card at least one other time and then make another dump?
