Summary

Electronic tags, also known as radio frequency tags, responders, and data carriers; Reader, also known as reading device, scanner, reading head, communicator, or reader/writer (depending on whether the electronic tag can wirelessly rewrite data). The spatial (contactless) coupling of RF signals between electronic tags and readers is achieved through coupling elements; Within the coupling channel, energy transfer and data exchange are achieved based on temporal relationships.

1. What is RFID electronic tag?

 
Composed of coupling elements and chips, each tag has a unique electronic code attached to the object to identify the target object.

2. Can RF tags be connected to sensors?
 
Sure, the RF tag has been connected to many sensors, including those that can record temperature and humidity. When environmental conditions change, tags can receive prompts, especially when the changes have a significant impact on the storage and use of items. For example, 2.4G tags can be connected to temperature and humidity sensors, as well as photosensitive sensors. The working principle is that the sensors are connected to the MCU of the tag, which collects sensor data and transmits it to the reader through 2.4G.


3. What is an electronic tag programmer?
 
Used for writing electronic data into electronic tags or accessing stored data in electronic tags

4. Common classifications of RFID electronic tags
 
1. Divided by the presence or absence of batteries
 
Passive RFID electronic tags, active RFID electronic tags, semi-active RFID electronic tags.
 
2. Divided by working frequency
 
Low frequency (125KHZ, 134KHZ), high frequency (13.56MHz), ultra-high frequency (840-960MHz), microwave frequency: 2.45-5.8GHz.
 
3. Classified by packaging process
 
Lebel paper labels, hang tags, PVC cards, ABS, PC plastic packaging, molding encapsulation, woven labels, non-woven fabrics, silicone, etc.
 
4. Classified by functional features
 
Ordinary labels, anti transfer labels, anti metal labels, anti liquid labels, anti freezing labels, high temperature resistant labels, LED luminous labels, etc.
 
5. Classified by application scenarios
 
Airline luggage tags, asset management tags, anti-counterfeiting traceability tags, clothing tags, tire tags, car windshield tags, medical test tube tags, unmanned retail tags, etc.
