Hello, We are using your bar code product Lic ver 3.0, the issue we are having when it reads bar code we see random numbers, also some of the tif file does not read. In the screen shot second part is bar code stating with 99 but first part (3141764) we are not sure where that came from. Sometimes it gives some random number our bar code starts with 99, Attach 2 screen shots examples. Here is the code we need your help.
thanks
Solomon
