POS Software?

[ocopus]

Anybody know of point of sale software for the pi (or am I the only person who's seen its potential in retail?)

[broo0ose]

Is this the sort of thing ..

http://lemonpos.org/

http://www.ghacks.net/2010/01/03/lemonp ... t-of-sale/

no idea if it will work on the Pi.

[SlikRick]

I am really interested in doing this with Floreant POS its a linux POS software. I have yet to try it out but would love to know if anyone has had any success with something like this?

[radio_davio]

I don't program POS, however, do use a lot of barcode scanners. So I'll be watching this too. Thanks.

I have been trying to install Openbravo POS since I got my pi. Yesterday I found simple instructions how to install JDK (Oracle Java SE Development Kit 7u6) that is needed to run Openbravo. Before I tried run it with open jdk, but couldn't make it work.

Finally Openbravo is running on my pi. I'm planning to use ipad with VNC client as a screen and to type in orders, receipt printer will be connected to pi. I haven't had time to try the printer with pi.

Overall It was pretty simple to install JDK and setup the database needed.

I'm also interested in getting openbravo installed, where did you find those jdk instructions?

also, anyone know of any pos solutions that would support credit card processing?

Not sure which instructions *gurro* used, but here is a link to the set of instructions that I posted on how to install the Oracle JDK 7 (Oracle Java SE Development Kit 7u6) on the Raspberry Pi.

I've been working on some POS software in python, but its not my strong point in programing. but I can really see the potential for the pi in this and stock control

[embeddedsys]

This seem intresting. Please post jpg or video of you setup and some screenshots of pos view in ipad

[qassoom]

I am really interested in this too! Looking forward updates on this page!!!

Would I be correct in assuming there's scope here to write some code for reading a chip & pin EMV card?

I have several chunks of code already in C#, all I would need is to figure out how to port them to another card reading system.

Essentially all I would need to change would be the calls to the underlying USB Card reader library.

or

Alternatively I could do an article on reading EMV on my blog then let folks translate it to a language of their own.

[dilleyboy]

I haven't finished the compile yet, but so far it looks like I might have figured out a way to get Openbravo running on my pi.
This is what I've done so far

How good would it be to attach a receipt printer, a cash register, and maybe a bar-code scanner to RasPi? If possible this would do a lot...!

[Shawty]

Most bar code scanners emulate a keyboard, so no extra programming would be needed for those, you'd simply read the standard input stream, and should get a stream of digits followed by a carriage return.

Most receipt printers use a standard line printer control set (Anyone who remembers sending individual Epson control codes to the LPT ports using different combinations of ASCII below 32 and above 127 will know what I mean) all you would need would be to either interface a USB serial / parallel device, or write directly to a receipt printer via it's serial USB interface.

The cash register on the other hand would be a very different kettle of fish, most cash registers use a proprietary serial based protocol, and you would need the manufacturers documentation to do it.

The good part is that most cash registers are serial based (normally RS232) so a USB serial device would get you most of the way there, but you'd still need to identify the most commonly used cash registers and decode the serial protocols.

I don't know if anyone has followed the walk through I posted, but my pi has crashed 2 times during the compile. I reniced the java process to 19 this time, and I think I know why it was crashing.

/home/pi/Openbravo-3.0MP17.1/src/build.xml:226: java.lang.OutOfMemoryError: Java heap space

I looks like the 512M on the pi just ins't enough. Does anyone have any thoughts on how to get around this?

Thanks.

[dilleyboy]

I have found that the 512MB on the model B is not enough for Openbravo to successfully install. I haven’t confirmed if this change will correct that issue, but I found two settings in the build.xml file that have to do with the max memory. Once my compile is finished, I will update this article
Here is the diff:

diff modified_build.xml build.xml

If anyone knows more about java than I do, I would like to know if this sounds like a potential fix.
Thanks

...
also, anyone know of any pos solutions that would support credit card processing?

this is what i hacked together to use the card reader:

Code: Select all

[schneidz@hyper temp]$ cat ./stuff/gcj/credit-card-read.c
#include "stdio.h"
main(int argc, char *argv[])
{
int i, c;
FILE * fstream;
fstream = fopen(argv[1], "r");
c = fgetc(fstream);
for(i=0; i < 4059; i++)
   fgetc(fstream);

for(i=0; i < 380; i++)
{
  if((i - 1) % 8 == 0)
printf("%c", c);
  c = fgetc(fstream);
}
fclose(fstream);
}

[schneidz@hyper temp]$ ./stuff/gcj/credit-card-read.x  /dev/usb/hiddev1

As I asked / Mentioned earlier. I have a ton of C# code for reading chip & pin / EMV, but it's all for windows and uses the PCSC Smart card interface, and only does chip & pin not magstripe, so you'll need a USB chip & pin enabled reader, plus the raspberry pi Linux smart card drivers & libs. Then you'll need to do some work to convert the PCSC calls to the calls needed to talk to the Linux implementation.

The higher level code however for selecting the payment application, getting the GPO/AFL objects etc then finally reading the EMV data objects is all there and all works wonderfully.

I'm actually in the process of updating the code to be more modern and easier to use, and turning it into a WPF based windows desktop analyzer application.

[dilleyboy]

Just to follow up with everyone. I was un-able to compile Openbravo on the pi. I was however successful with LemonPOS. I found the Ubuntu walk through for compiling Lemon POS was close enough for Wheezy. If anyone needs help with that, I will post a walk through shortly.

[dilleyboy]

Here is the walk through for LemonPOS http://dbc-customs.com/?p=77
Now we just need to figure out a cash drawer. From What I can tell, there are some barcode scanners, and thermal printers that will work with Linux already. For the thermal printer, we just need one that comes with a CUPS driver, and LemonPOS will integrate with that, and barcode scanners are more or less an input device like a keyboard, so it will just read the barcode, and type out the contents.

[techwizard10]

I just installed LemonPOS on my Pi, and I used this wish list on Amazon.co.uk to get all the stuff I needed.

[dilleyboy]

That's a great list! Do you have everything up and running now? Did you use my walk through to get LemonPOS installed, or have you found a more efficient method?
Thanks for sharing!

A tutorial would be greatly appreciated!!!
