Mifare classic S50 Increment, decrement and Resotre Operand

Question asked by Taloya Tan on Oct 20, 2017

Hi, I am developing driver for Mifare classic S50 reader. I am confusing about the data format of 4 byte intger Operand of M1 card command Increment, decrement and Resotre. Whether MSB or LSB is used for the Operand?  I can not find the answer from document "MF1S50yyX/V1".

 

If I want to subtract one from value block by decrement command, should I specify 0x01 0x00 0x00 0x00 as an operand? Or should I specify 0x00 0x00 0x00 0x01 as an operand?
