scanners with a bit of custom code

Hi,
we have a client who wants to do the following
- scan a bar code on a vaccine
- have the scanner request the last 4 characters of the batch number
- user enters batch
- next scan, etc...

At the end of the day, our 4D app sucks down the data. We can do this  
bit (thanks to friends on this list)
The bit we're stuck on is finding the right combo of scanner with a  
full alpha numeric keypad and a small application for the scanner that  
allows us to program it easily to request a batch number.

We have found a small application that runs on Windows CE scanners,  
but that seems to require a sync to move data to a folder, then 4D  
gets it from the folder- we'd rather just go straight scanner to 4D

Thanks in advance,
