I remember reading somewhere that you could take an amex dump and just change the 201 to 101 and run it as if it was a no chip card is this true? Doesnt sound right to me, but I could be wrong.. Also does bypassing (1 dip, 3 dip) work with discover?

yes. this is real. but just change 101 is not working. if you need . i can help you.

yes that true , but that happened before years ago, but any way depend the network and depend the bank and country , this filed in ISO 8583.this is in protocol of bank to server but mostly of banking is fixing that , i used that way before 3 years ago and not is stopped
so try bro you never lose nothing https://txgate.io/images/smilies/smile.gif

number1234, I seen you post that you can change service code from 201 to 101 on amex cards. Is this with certain banks or bins. I'm really interested to find out about this. I do in store and this would be very helpful for me. Which banks do you know this work for. I'm only interested in centurion.
