2.20 How do bar codes work?

A wedge bar code reader connects between the keyboard and the PC. When the reader scans a bar code, the reader decodes the bar code and squirts the characters to the PC as though a person typed it. Therefore, our software can't tell the difference between the reader and the keyboard, and any wedge bar code reader should work.

Compatibility issues are between the bar code labels for the books and other materials and the patron cards: you want a bar code reader which will handle all. In other words, don't get a bar code reader that will decode your book labels but not your patron labels. CyberTools does not require a specific bar code symbology.
