Barcode and RFID are technologies used to read and collect data. Both of them work differently. However, these technologies are mostly by companies to track assets and inventory. Generally, their differences come in the way they work together with their capabilities. Though RFID has a more extended history of use than barcodes, barcodes seem to play a huge part in most industries given its benefits over RFID. Depending on your activities, you may choose any option.

This article will help you to understand how both barcode and RFID works.

Barcode Technology

Today, most businesses are adopting new technologies to enable them to beat the ever-rising market competition. The use of barcode is among other incredible technologies that you will find in almost every company. Particularly, this technology is used to track stock inventory, and it enables swift checkout.

For a better understanding of how barcode works, the are two main concepts. A scanner decodes the black bars, which are in the form of serial numbers and the data collected is transferred to the computer that interprets the information. Generally, this information contains details about the product, including the product ID, the manufacturer and price.

RFID Technology

As the name suggests, Radio Frequency Identification uses radiofrequency. For effective use of RFID technology, one must have tags and RFID readers. Each tag contains the products’ information. The tags are different, and the most used tag includes the identification number of the product. In contrast, others are capable of holding data of at most 8 KB including the price, colour, manufacturing, shipping and expiration date, and maintenance history.

Each tag must have a radio antenna for it to obtain signals from the readers. In other cases, some readers have their antenna enabling them to write information to the tags. The reader also sends information regarding the product to the computer.
