A few month ago, I had an idea for a real cash register for children.

And of course this would be a nice project to get hands dirty in some hardware and software…

…so, I started to think about: What should be part of the cash register?

By that thinking, I asked myself: What parts belong to an actual cash register?

So here are the parts:

• Bar code scanner
• Receipt printer
• Cash register
• Credit card reader

Now, where the hell should I get these parts from? Of course as cheap as possible… :)

Solution: Some kind of flea market. Or better: (in Germany) ebay-kleinanzeigen.de

So I found the first three parts. (I will introduce the parts in a later article) The last one, I already owned. (Means: I owned a rfid reader, which is sufficient)

Bar code scanner

Receipt printer

Cash register

Now, I’m waiting to get the parts…

And, in the meantime I do some testing with my rfid reader…
