RFID technology and its applications in manufacturing.

1. What is RFID technology?

RFID (Radio Frequency Identification) is a technology that uses radio waves to automatically detect and track labels attached to objects. In other words, RFID is a remote radio frequency identification system that allows data to be read and "dissociated" to explode in the radio waves at a distance of 50 cm to 10 meters.

Use RFID tag devices and RFID readers. The key to RFID is that it's a technology that doesn't use radiation like barcodes and doesn't create an instantaneous connection. Some tags can be read from environments and other harsh environmental conditions where concrete, snow, fog, ice, paint, and barcodes and other technologies cannot detect and interact effectively.

2. RFID System

– A minimum RFID system includes the following devices:

+ RFID tags: chip-embedded tags + Antenna

RFID tags can replace labels on products sold in supermarkets. Instead of moving a device close to the barcode to scan it, RFID allows information to be transmitted over short distances without physical contact.

RFID tags are used in many fields such as: personnel management, product management inside/outside supermarkets, warehouses, animal surveys, vehicle transportation through customs, work, passports, etc.

There are two types of RFID tags: passive RFID tags and active RFID tags .

• Passive tags :: No external power source required; receives power from the reader; short reading range.
• Active tags :: Stored with a PIN code, used for remote reading

+ RFID reader (also known as a reader-reader): reads information from the badge; it can be attached or detached. – Antenna: connects the badge to the reader.

• Antenna: receives a radio signal to activate and communicate with the label.
• Server : requires services for accessing and processing data, monitoring, statistics, management, etc.

3. RFID applications in manufacturing

– With the support of RFID technology, a great deal of human labor has been reduced and replaced by a system of equipment that is more efficient and of higher quality.

– In warehouse management, RFID systems are used to easily classify raw materials and products in the warehouse using RFID tags attached to each material and RFID readers. Actual warehouse data such as location, quantity, and classification are collected, stored, and displayed on the warehouse's server system by the RFID system. This allows for faster and more efficient control of import and export operations.

Applications of RFID in warehouse management

– By producing products online, RFID systems help to better control the production line by replacing Kaban tags, clearly identifying the level of work done on finished products at each stage of processing and monitoring in real time. In addition, this control helps avoid delays in assembly or semi-finished product production.

– By storing and transporting products to the consumption system, the RFID system transmits this information to the control center to monitor temperature and humidity. This information helps to better control the product.

With the development of the 4.0 technological revolution , the integration of RFID and its applications will continue in the future, helping to create smarter companies.
