No, they're dual core pc's with 2gigs of ram running XP and a custom POS frontend.
I used to work for Torex, who are one of the biggest players in the EPOS market, and i can tell you now, most of the PC units dont have dualcore PCs. The spec of the box's is truely trafic. Old pentium 4s etc..
They have stockpiles of old PC units which mean the customers dont get newer kits unless they ask for it, despite the fact that the processors have long since gone out of production.
I'll skip to you parts that actually warrent a reply.
So you're saying that hitting £5, then entering chage of £1.95 is faster than keying in £3.05?
The industary I work in requires audit trails for every transaction down to the penny, and I don't just mean amounts I mean notes and coins etc. It's a multi million pound business where over half the transctions are cash. And no it's not drug dealing.
I'm sorry if I've offended anyone who works in the cash register industary. I was just judging things by my experiences.
This largely comes down to the EPOS software in use by the shop.
Some use "shortcut buttons" on the touchscreen unit attached to the PC unit. This gives the user a choice of pre defined ammounts that the customer may enter. The £5 in this case would have been one of those buttons. Thus, telling the EPOS software that the customer gave £5 is just a single button press.
Because £3.05 is an exact ammount, there is no preset for this, the user has to press exact ammount button, then manually key in £3.05, so about 4 presses more.
But this isnt the same for every EPOS. Torex offers over 10 different pieces of EPOS software, largely down to hostile takeovers of its competition offering cometing products. Each one is different. Some of them are a joy to use and java based. Others, like lucas are a pain to use and are far from a joy and dont have shortcut buttons at all.
It all depends on the shop, as different customers require bespoke versions of the software. Retail Java is one of the most ubiquitous pieces of EPOS software, but it rarely looks the same from one shop to another as it has customisation built into it from the ground up.
