What is RFID?
RFID stands for Radio Frequency Identification. It refers to small electronic devices that consist of a chip and an antenna. The chip typically holds up to 2,000 bytes of data or less.
The RFID device functions similarly to a barcode or a magnetic strip on a credit card or ATM card. It provides a unique identifier for the object. Just like a barcode or magnetic strip, an RFID device must be scanned to retrieve the identifying information.
A basic RFID system includes tags attached to items that need to be tracked. These tags, made from a tiny chip and known as integrated circuits (IC), are connected to an antenna. The antenna can be integrated into various tags such as apparel hang tags, labels, security tags, and industrial asset tags. Each tag contains memory that stores the product’s unique identifier (EPC) and other important data, enabling it to be tracked and identified by a UHF RFID reader.
The UHF RFID reader is a network-connected device that can be either fixed or mobile. It features an antenna that sends power to the tags and receives signals from them. Essentially, the RFID reader acts as an access point, making the tag data available to business applications for tracking and management.
