RFID labels

An RFID label (also called RFID tag) is a type of label powered by RFID technology.

An RFID is composed of three elements: an RFID chip, an antenna and a substrate.

The RFID chip and the antenna are attached to the substrate. The chip stores and sends information via the antenna to a so-called RFID reader.

The way in which the information stored in the RFID chip is transmitted to the reader varies depending on whether the chip is passive or active. When the chip is passive, it means it uses the energy generated by the RFID reader to transmit the information. Active chips, on the other hand, possess an on-board battery that transmits the chip’s identification signal.

Compared to traditional labels, RFID labels offer several advantages, including the following:

• They do not require visual contact. Unlike barcode labels, which do require visual contact with a barcode scanner, RFID labels can be scanned without ever getting into visual contact with the RFID reader.
• They can be scanned in bulk. Traditional labels must be scanned one by one, which increases the information collection time. RFID labels, however, can be scanned simultaneously, making the reading process a lot more efficient.
• They can encrypt information. Instead of allowing anyone to scan the information, the data encoded in the RFID label can be encrypted so that only authorized personnel are allowed to read it.
• They are resistant to adverse environmental conditions. In this sense, RFID labels can withstand cold, heat, moisture or humidity.
• They are reusable. Unlike barcodes, which cannot be edited after they have been printed, the information contained in the RFID chip can be altered and the RFID label reused.

Considering the multiple advantages that RFID labels offer, manufacturers are slowly turning to them and abandoning the old barcode system.
