Applying RFID technology in practice.

RFID technology stands for Radio Frequency Identification. It is a remote radio wave identification technique that allows data on a chip to be read "contactless" over a radio wave transmission path at distances ranging from 50 cm to 10 meters, depending on the type of RFID tag.

Applying RFID technology in practice.

Access control systems are stored within the access control system, and each person is connected by a unique number. This number is stored on an RFID tag. If the access control system receives information from the card reader, it searches the database to see if the person has access rights. In this case, the system sends a signal to the door to open it.

RFID can be used to identify healthcare facility clients, animals in live animal management systems, students using luggage lockers, and taxis requesting access to airport reception areas.

Additionally, RFID technology is also applied to online product management systems for livestock, enabling automated feeding or milking and detecting maximum heat sources. Traffic control uses RFID on buses, taxis, and ambulances to ensure safe and comfortable access to bus stops, taxi stands, or priority lanes. Stores use RFID for security and inventory control. Transportation departments use RFID to track packages in warehouses and during transit.

RFID tags can be affixed to any product, from beverage containers, shoe soles, and jeans to car axles. Companies simply use computers to remotely control the products. RFID can replace current barcode technology because it not only has the ability to identify the origin of a product but also allows suppliers and retailers to know exactly what items are on the table and in stock. Retailers no longer have to worry about inventory control, fearing misunderstandings, and statistics on the quantity and products sold in the store. Additionally, they can also know exactly what's in a customer's bag.

When RFID is added to a product, it immediately emits a radio signal indicating the product's location—whether in a shopping cart, cold storage, or retail store. Because the device is connected to the store's computer network, the salesperson can know precisely when the product was manufactured, shipped, its color, and size; and what temperature should be used for proper storage.
