A barcode is a commonly used design element for ID cards. Barcodes can add functionality to any ID card program allowing cards to be used for applications such as time and attendance tracking, cashless payment, customer loyalty cards, and more.


Barcodes consist of printed and variously patterned bars and spaces, and sometimes numbers. The code is then scanned and read into computer memory that contains information about the object that is labeled.


Barcodes come in 1D and 2D varieties. 1D barcodes, or one-dimensional barcodes, consist of a single row of bars that store a smaller amount of information in a horizontal width. These types of barcodes are best suited for types of applications where fewer characters are stored. 2D barcodes, or two-dimensional barcodes store more information than their 1D counterparts and have both horizontal and vertical dimensions for holding data.
