UHF RFID READERS AND TAGS
SYNOTAG UHF RFID readers and tags operate at 860~960 MHz with reads of up to 10 meters, depending on the tag and the reader used.
Combine our UHF RFID tags with our fixed or handheld UHF RFID readers that are built tough and come with an SDK (C++ and C#) for easy integration into your system. Some of our readers can be customized with optional GPRS/GSM, CDMA and 802.11 Wi-Fi modules to address your specific project needs.

WHAT IS A UHF RFID SYSTEM?
SYNOTAG UHF RFID tag and reader systems use 860-960 MHz radio waves to identify items, assets, vehicles and people at distances ranging from 1-10+ meters. Like any other type of RFID system, a tag, a reader and a software application/database are all required to make UHF RFID system functional.
SYNOTAG UHF RFID tags are passive and mainly follow the EPC Global Gen2 (ISO 18000-63) UHF standard with ICs that range from 96 bits to 512 bits memory. The reading speed of UHF tags is much faster than either HF and LF tags and price per tags is generally lower. UHF tags can also be read at and written to from longer distances, but for some applications, you may not want an array of different UHF tags all being read all at the same time.
When choosing the right UHF tag for your application, you should consider factors such as the size, the expected antenna orientation at site, the reading angle and the area where the tag and reader need to function. Liquids, metals and people all have a tendency to reduce the read ranges when using a UHF tag that is not specifically designed for those special applications.
We offer many types of UHF readers to meet every requirement, from fixed to portable and desktop USB readers. When choosing a reader you should consider the following factors:
- The Reading Area: A fixed reader is mounted and oriented to cover one specific area like a doorway, a production line, a conveyor belt, or a delivery bay among many other types of applications. Hand held readers are more suited to application where we need to search for a UHF RFID tag that otherwise ill not come into range of a reader, such as those on shelves in a warehouse.
- How Many Tags to Read at Once? Consider how many tags you want to read at one time. Do you really want to read 20 or 200 items at once? Or do you need to read them one by one?
- Antenna Type: Circular polarization antennas are the best choice for use in environments where the orientation of the tag can change. For example, in a doorway where people will walk in and out with a UHF tag on a lanyard or for a car parking area. Linear polarization antennas are best used when the orientation of the tags is known and always the same, such as on a production line or conveyer belt type operation.
- Number of Antennas: Our high-performance readers have 2 ports, 4 ports or 8 ports. The number of antennas to work with is normally based on the reading area that we want to detect or the number of tags we need to read. Most applications use 2 or 4 port fixed readers.
- USB UHF Readers: Perfect for reading in tags during a manufacturing processes or for validation of single documents. Can be used for access control in some situations.
- Passive tags that can be read at long range of 10+ meters
- Relatively low cost with fast reading speeds and flexibility with memory size
- Scanning many items at one time
- UHF tags affixed to metal, liquids and people all have a reduced read distance
- Multiple tag scanning is not desired for some applications and can cause misreads and collisions
- Readers are more expensive than LF and HF tags, driving up overall system costs
