Common Questions and Answers for RFID Tags

What is the RFID tags?

 

Electronic product code is the development of global product code, which can identify targets beyond the horizon. Electronic product code is not just a radio bar code, but contains a series of data and information, such as origin, date code and other key supply information, which is stored in a small silicon chip. With tags, interpreters and connected computers, producers and retailers can know accurate product and inventory information at any time.

 

What's the price of the RFID tags?

 

The price of RFID tags varies from 30 cents to 50 dollars depending on the type of tags and application price. Generally speaking, smart tags used in high-end products are more than 50 cents, and active tags are much more expensive, and the price of complex sensitive components is more than 100 dollars.

 

Can RFID tags be used for metal objects? Can it be used for articles with high water content?

 

Yes. Radio waves are reflected back from metal objects and absorbed by water. This makes it difficult to track metal objects or objects with high water content. But well-designed systems can solve these problems.

 

How much information can RFID tags store?

 

Tags can store data ranging from 512 bytes to 4 megabytes depending on the type of business. The data stored in the label is determined by the application of the system and the corresponding standards. For example, labels can provide information about production, transportation and storage of products, as well as identification of the machines, animals and individuals. These are similar to information stored in barcodes. Labels can also be connected to databases to store product inventory number, current location, status, price, batch number information. Correspondingly, the RFID tag can directly determine the meaning of the code without referring to the database when reading the data.

 

Can RFID tags be connected to sensors?

 

Yes, the RFID tag has been connected to many sensors, including those that can record temperature and humidity. When environmental conditions change, labels can be prompted, especially when changes have an important impact on the storage and use of items.

 

What's the difference between transponder, smart tag and RFID tag?

 

At first, in the field of technology, transponder refers to the electronic module that can transmit information and reply information. In recent years, due to the rapid development of radio frequency technology, transponder has a new concept and meaning, also known as smart tag or tag. Intelligent tag is exactly an innovation of radio frequency tag, which consists of sticky tag and ultra-thin radio frequency tag. Intelligent tag combines the advantages of radio frequency technology and convenient and flexible tag printing. Intelligent tag with read and write function can be programmed many times, following the coding rules of the original tag production.

 

Which label is suitable for my customer's product?

 

Can labels work properly in water? Will metal destroy its function? What temperature does it work properly at? Products of higher water content, metal products, high or low temperatures can be a challenge to labeling. But carefully designed systems can overcome these shortcomings, so the types of tags are also very different according to the different application functions and objects. The purpose of RFID tags is to use a unified standard of electronic product code so that products can be identified in different fields.
