What is a Barcode Reader?

A Barcode Reader is an electronic device used to read and interpret barcodes. It consists of a scanner, decoder and software that work together to quickly identify items.

How Does a Barcode Reader Work?

Barcode Readers use light-emitting diodes LEDs or lasers to scan barcodes on products, labels or tags. When the scanner passes over a barcode, it reads its unique pattern of black lines and white spaces. The reader reads the barcodes, the decoder translates the code into digital data, and the software interprets this data so that it can be used by a computer system.

Barcode readers can be found in many places, including grocery stores, warehouses, and libraries. They save time and reduce the chances of errors by quickly identifying items and providing accurate information. Additionally, barcode technology has revolutionized industries such as healthcare, where it is used to track medications and medical equipment.
