... Barcode Format
A barcode is a series of vertical bars of varying width
representing numbers or letters. The Dynix system uses standard
Codabar 14 digit barcodes. A patron barcode starts with the number

In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system, or base-2 numeral system, which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). The base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices. Each digit is referred to as a bit.
