Introduction the Difference of RFID Tags

You may confuse about the difference of UHF RFID tags and LF and HF RFID tags:
UHF RFID tags (UHF):
UHF RFID tags referred to as microwave radio frequency tag and microwave frequency bands commonly used electromagnetic emission principle.
Size (mm): 112*24 mm, 50*25mm
Protocol: ISO18000-6C
Material: Polystyrene
Frequency: 860-960MHz
Chip options: Alien H3, Impinj M4
Write cycles: 100,000pcs
Protection level: IP 54
Application: Widely used in inventory control of expensive electronic assets, supply chains that use metal carts, tracking of metal tools, and warehouses with metal racks could all benefit.
Mode: read-write
1. Passive UHF RFID tag long range distance, up to 10 meters.
2. UHF role in a wide range is the most advanced networking technologies are using UHF RFID technology.
3. To transfer data faster, per single tag read rate of up to 170 / sec
4. The label store large volumes of data.
5. UHF RFID flexibility can be identified easily obtained.
6. The high data transfer rate, in a very short period of time a large number of electronic tags can be read.
7. The anti-collision mechanism for multi-tag read, a single batch can read multiple RFID tags.
8. The electronic tag antenna is usually long and label shape. Linear and circular polarization antenna has two designs to meet the needs of different applications.
9. The handheld reader for UHF RFID tags can be read or written.
10. A handheld reader for UHF RFID tags can be batch operation.
11. Handheld reader with CE operating system read UHF RFID data, through WIFI, GPRS real time upload to the back-end database.
12. Handheld reader quite a PDA computer, by reading UHF electronic tag data read and write operation can be completed in handheld readers and hand-held reader can instantly query tag data. (Such as manufacturer information, batch number, production date, etc.)
13. UHF RFID tags with a global unique ID number, security is strong, not easy to crack.

Low-frequency (LF) and high frequency (HF) RFID Tags
This kind of RFID tags commonly used electromagnetic coupling principle like LF cattle RFID bolus. High frequency typical operating frequency is 13.56MHz. The band RF tag, because the low-frequency tag works exactly the same principle, namely by inductively coupled manner, so should be classified as low-frequency tag class. On the other hand, according to the general division of radio frequencies, also known as high-frequency band of its work, it is also often referred to as high-frequency tags.

Specification:
1. The effect of low frequency range is now mainly used in the technical field within the low end of the range, such as automatic parking fees and vehicle management systems.
2. The data transfer speed is slow.
3. The label store less data.
4. Low frequency electronic tags inflexible cannot easily be identified.
5. The data transmission rate is low, in a short time can only read one tag.
6. Only suitable for low-speed, close-recognition applications.
7. Compared with the ultra-high frequency electronic tags, tag antenna turns more and higher costs of some.
8. Only one read electronic tag data read.
9. A hand-held reader can query data in real time.
