Common guys I dont know how to explain you this. Ok I bought upgrade software from PAR to upgrade from PAR 6.52 TO PAR 6.6 so that I can use integrated credit card payment system in POS itself. After installing software, I have to enter following FEF code (03 03 A1 02 06 00 03 00 FF FF 34 5E 31 98 74) to activated payment function in POS menu. It is the same program for all stores except FEF code or key is different to activate in menu. My question is I saw FEF code for other store and the only difference between mine FEF code or key and other store is from (34 5E 31 98 74). The last five numbers are different. Is that store number or what? That's what I want to know. I dont want to keep buying software for each store but I have to do that cause PAR provides with FEF code. I was wondering if I can figure out last five numbers in FEF code by myself since first 10 numbers in FEF code is same for any store. Thank you
The data from the POS terminal should normally be well protected. Having an extra POS terminal to hack the internals of before swapping with the real terminal is an attack regularly used. Normally, the shop gets a burglary but can't figure out what was stolen. Then a couple of days or weeks later, they get a second burglary. Once or twice, the company has had an inside man - Toys-R-Us in Sweden did suffer from that last alternative a year ago.
Having a stolen POS terminal that is intended to be swapped with another terminal obviously requires the stolen terminal to be upgraded to the required feature level before the swap, or the shop owner would immediately call and complain that one function has stopped working. A visit to the service menues would probably instantly tell that it has the wrong serial - or store - number.
What we can tell, is that this is not a person who should receive any help. And that is the general case whenever questions about point-of-sales equipment are asked. The only good POS questions are: Who sells xxx, which one is better or similar.
"Who sells xxx, which one is better or similar."
Which is, clearly, entirely off-topic for this forum anyhow!
