I have an app currently which enters Invoice details as follows:

Cust No. etc..... (Invocie Header)

and allows multiple detail lines in Invoice Detail as follows:

Stock Code :
Price:
Qty:

I want this to be used at a Point of sale with following changes:

1. When it asks for Stock Code, to Scan In a stock code from a product
2. Once all detail lines are entered, the system to automatically open a till drawer.

So realy what I'm wondering is how easy / practical is it to add Bar coding and a Till functionality to the App.

Regards,

Gerard
