1D/ Linear Barcode
There are two main types of barcodes: linear (or traditional) barcodes and 2D barcodes (such as QR codes). 1D or linear barcodes hold one piece of information, normally an identifying number that the company’s central database uses to find product information, such as price and remaining quantity.
2D barcodes (such as QR codes)
2D barcodes can hold way more data, including the price and quantity but also photos or links to web pages for related information. Employees use barcode scanners, mobile computers, or smartphones to connect the company database wirelessly or through Bluetooth to their warehouses or other remote locations. Barcodes can be printed directly via a variety of barcode printers, depending on the company’s needs.
