POS Integration

Hey Gurus...
Any ideas how make integration with a Cash-Register, BarCode Readers and so on...
Bar code readers generally just emulate keystrokes so usually you don't need anything special for them.  For more complicated POS devices, generally they have an SDK and/or examples in Java or .Net showing how to communicate with those devices.  Get the Java or .Net solution to work and then just pull that code into an extension using Integration Studio.

Hope that helps,
Thanks for your quick response...
When you say " They have an SDK" you mean Vendor?
Do you have or anybody have any clues or example? 
Best Regards
Yes, the vendor.  I would have to know the make and model of your POS devices to have more clues.
