What is radio frequency identification? ｜ Advantages and disadvantages of RFID

RFID is a system that reads and writes information in a non-contact manner by updating the electromagnetic force between the "tag" attached to the product and the "device" that reads the tag.

By using RFID, radio waves can be used to scan multiple tags at a time. Normally, barcodes attached to products are scanned one by one using a laser or the like.

There are four types of RFID, "communication method", "frequency", "access" and "read".

The biggest advantage of RFID is that it can improve work efficiency. Due to the nature of ordinary barcodes, they need to be scanned and checked one by one, which is time-consuming and labor-intensive.

Using RFID, multiple product information can be read at once, thereby reducing the burden of product arrival, inspection, and inventory.

RFID has several advantages, but there are also disadvantages.

The use of RFID requires a dedicated data-based management PC, a dedicated reading device, and an RF tag to read the data, so its disadvantage is that the installation cost is higher than that of a barcode.

Another disadvantage of RFID is that when the product information cannot be read due to some errors,

It is difficult to identify radio frequency tags. When introducing RFID, it is recommended to firmly determine the working rules.
