Hello, I'm a certified developer and have extensive experience developing, I have an application that reads bar codes, only it would have to adapt it to your precise requirements, this should take me less than 24 hours, if you send me some codes you need to read and as they should be interpreted, it would be good, so I say if my reader will read them without problems and gives the output as your needany questions I am to your orders, best regards, GCG
