Understanding RFID Connection in Electronic Price Tag Networks
What Is RFID?
Radio-frequency identification, or RFID, is a technology that uses electromagnetic fields to identify and track objects automatically. In retail, RFID enables stores to manage inventory and pricing with greater speed and accuracy.
How RFID Works
RFID systems rely on three main components:
- RFID tags: Each tag contains a microchip and antenna. The microchip stores unique data, while the antenna enables wireless communication.
- RFID readers: These devices send out radio waves to power passive tags and receive data from them. Readers can be fixed in place or mobile, depending on the store’s needs.
- Software: Middleware and dashboards collect, aggregate, and integrate data from readers with central retail systems.
When an RFID reader emits a signal, it activates the tag’s microchip. The tag then transmits its stored information back to the reader. The reader forwards this data to the network, where software processes and stores it for further use.
Types of RFID Used in Retail
Retail environments typically use three types of RFID tags:
- Passive tags: Powered by the reader’s signal, these tags are cost-effective and suitable for most product tracking network applications.
- Battery-assisted passive tags: These tags use a small battery to boost signal strength, increasing read range.
- Active tags: Equipped with their own power source, active tags offer the longest range and are used for high-value assets.
Most retail RFID systems operate in the ultra-high frequency (UHF) range, between 860 MHz and 960 MHz. This frequency supports fast data transfer and longer read distances, making it ideal for inventory and price management.
What Are Electronic Price Tags?
