Vladimir, Thank you for your reply. The barcode readers is parallel connected with the keyboard. It reads data and send it to the keyboard buffer. At the end of data it sends a .
We are handling book's barcode. The following is how the readers gets wrong data.
Original Barcode 9781568840864 case 1 [879]1568840864 [879] in reverse order case 2 9781568[468048] [468048] reversed case 3 978156884[4680] [4680] reversed
Basically part of the digits reverse their order. Have you seen this before? At the moment I need to add codes to verify the barcode again after a SEEK since case 2 may get the wrong book.
TIA
