Great video FoxLearn!!! Is there a way to do the exact same but only for the program to read numbers instead of a barcode?

[@pusulaelektrikotomasyonrob6563]

I have made same, it is working very good, many thanks. I have question: It can read barcode only while straight or reverse. it can not read it in cross position with an angle. how is possible to read barcode in cross position ?

Instead of scanning with webcam , I would like to scan with bar code scanner device then what should I have to do ? Could you give me any reference for me ? Thanks

[@KNHSynths]

a barcode scanner directly sends the code to the application... so nothing to do. Most of them can be recognized as a keyboard. So just connect the device to USB port, and wait for the text to come... Some devices are asking for a bit more connectivity (serial port for example), but it is not a barcode problem, it's another story, serial devices connection. All will depend on the device you want to use. If you have the choice, select one that work like a keyboard, zero code :-)
