Dear Ritesh Gupta, thanks for your reply,
at this time i do not use Rhoelements, i just can read the scanned barcode whicht is working with the doScan Method like described above. I try now to get a RFID scanned tag (id) into my jsf application.
Which possiblities exists doing that? except programming a fat client
Is RhoMobile with WTG_RFID_PLG.dll the only way doing that?
