In this article, we will focus on the difference between barcode reader (barcode scanner) and RFID reader (RFID scanner) to learn more about these two types of devices.

Summary: The difference between a barcode reader and an RFID reader is that a barcode reader, also known as a barcode scanner, is an optical reader that uses a laser beam to read barcodes. While RFID (radio frequency identification) is a technology that uses radio signals to communicate with a tag placed in or attached to an object, animal or person.

A barcode reader, also known as a barcode scanner, is an optical reader that uses a laser beam to read barcodes. A barcode is an identification code consisting of a set of vertical lines and spaces of varying widths or a two-dimensional pattern of dots, squares, and other images. Barcodes represent data that identifies the manufacturer and the item. A newer type of barcode, known as a 2-D barcode, can store more data than traditional linear barcodes. Manufacturers print barcodes on product packaging or on labels affixed to products.

RFID (radio frequency identification) is a technology that uses radio signals to communicate with a tag placed in or attached to an object, animal, or person. RFID tags, which contain memory chips and antennas, come in many shapes and sizes. The RFID reader reads the information on the tag via radio waves. RFID readers can be handheld or mounted in a fixed object such as a doorway.

Many retailers consider RFID as an alternative to barcode recognition because it does not require direct contact or on-site transmission. Each product in a store will contain a product identification card. As the consumer takes the product off the shelf and walks through the checkout area, the RFID reader reads the card(s) and communicates with the computer to calculate the amount due. Other uses of RFID include time tracking of marathon runners; track the location of soldiers, employee wardrobes, airline baggage, and lost or stolen goods; check lift tickets or skiers; inventory management; measure the temperature and pressure of the tires on the vehicle; check library books; and track the payment as the vehicles pass through the stations on the toll collection system.
