[xVar]

Hi!
I probe use motorola MC 9090 PocketPC with BarCode and RFID reader.
Unfortunatly, I can't find any documentation for RFID DLL's.
But I find Datawedge application for motorola. It's work with Barcode reader, but not work with RFID reader.
Use anybody this aplication with RFID?
Also I seek for any documentation about motorola RFID DDLs.

Andrej.
