WCR3237-600USBarcodes are an extremely common card feature because they can be printed by every ID card printer and encoded by almost all design software. But when you have to choose between 1D and 2D barcodes, do you know which one you need?

1D Barcodes

1D barcodes are the simple vertical line barcodes you see on cereal boxes, library books, and airline tickets. These barcodes hold small amounts of data and, depending on the style, can only hold up to 25 characters of data.

You may want to use 1D barcodes if you are printing basic ID cards without complicated uses, or your software only encodes 1D barcodes.

2D Barcodes & QR Codes

2D barcodes go far beyond the basic vertical lines of the 1D style. Designed with squares, dots, horizontal lines, or other patterns, 2D barcodes give you more options for customization. 2D barcodes can hold larger amounts of data, so these may be a good option if you need more than 25 characters. QR codes are the most commonly used types of 2D barcodes.

2D barcodes do require special barcode readers, so they may not work with your existing equipment. Not all card software can encode 2D barcodes, so make sure your software edition has this feature.
