What is the special feature of revealing RFID RF soft tags

You may often see anti-theft soft labels on products in supermarkets, cosmetics stores, and pharmacies. Soft labels are easy to use, have good anti-theft effects, and low costs, and can be directly pasted onto products. There are two types of anti-theft soft tags: acoustic magnetic soft tags and radio frequency soft tags. There are various shapes, such as squares, rectangles, circles, irregular shapes, etc. Among them, RFID radio frequency soft tags are currently popular tags. Do you know its characteristics? If you don't understand, come and learn more with me!

RFID radio frequency soft tag can be considered as an electronic version of barcode. Its working principle is based on the radio principle, which obtains the number information in the RFID tag chip through processes such as electromagnetic wave carrier and modulation. The working frequency of the RFID tag is 8.2MHz, and the detection distance is 0.8-1.2 meters. It is cheap and reliable, and suitable for various commodities.

RFID radio frequency soft tag has the following characteristics:

1. RF soft labels cannot be directly attached to metal or foil products.

2. RFID RF soft tags cannot overlap (two or more).

3. The placement of labels should be as flat as possible. The adhesive surface should be as small as possible and not folded. Cannot be less than 120 degrees.

RFID tags are usually more sturdy and durable, not affected by the environment, and can withstand high temperatures and water, as well as harsh environments such as acid and alkali.

5. RF soft tags have a large storage capacity compared to traditional forms of tags (1-1024 bits), and the data can be updated at any time.

6. RFID tags are not like barcodes, their unique identifier cannot be copied, they are special numbers. The content of the tag can be read and written repeatedly.
