Barcode scanner dll

Can I read UPC-A, UPC-A supplement 2-digit barcode and UPC-A supplement 5-digit barcode directly from barcode reader & transfer that data in to the database? How can I do? Thx
Definitely you can transfer the data. But you will need a hardware barcode generator and software to decode barcode that support UPC-A, and UPC-A with supplement barcode.

No doubt barcode scanner hardware is the most convenient one. However, if you use in programming, I suggest you to use a .net one.
