TTL UART Long Range UHF RFID reader Module (ISO18000-6C EPC G2) is an important
way to read information and input information. Automatic identification technology has been
developed in recent years. Now it is a new high technology which includes barcode
technology, magnetic strip (card) technology, RF technology, optical character recognition
technology, and biological recognition, distance Card Reader and etc.
In normal case, UHF RFID tags need less power than the reader which needs to have high
receiving sensitivity. In certain system, the transmit path and receive path are independent
of each other in the reader, especially when the uplink and downlink have different
frequency.
Technically, different applications can choose different transmit power. However, there are
regulations that need to be met. Usually the RF power 100mW~500mW is suitable for all
kinds of RFID distance reader system. In different regions and areas, the reader has to
follow different regulations.
Linksprite UHF RFID distance reader has many advantages such as: compatibility with
different protocols, high reading speed multi-tags reading, linearly polarized antenna,
waterproof appearance designing and etc. It can be widely used in RFID systems, and is
very friendly to further development based on it.
Typical applications:
� Logistics and warehouse management: Management of goods flow and storage, and
mail, package, luggage transportation and etc.
� Intelligent parking management：Parking management and charge automation.
� Production-line management: Identification of production process points.
� Product anti-counterfeiting detection: the write protection from tag’s internal memory
can be used to detect the products’ authenticity
� Other application: widely used in club management, libraries, student status,
consumption management, swimming pool management and etc.

When the UHF RFID reader (USB version) is powered on and connected to PC, it can be
identified by the PC. It uses the HID USB driver, and doesn’t need additional USB driver. It
means the reader is working normally. When the tag is close to the reader, the PC
software will show signal strength and tag ID. This RFID reader can identify many tag IDs at
the same time.
Note: It needs a 3V/2A wall adapter.
This UHF RFID reader uses RF energy harvest to read tag data. Keep it far away from
metal when use it. If it closes to the metal, the RF wave will be absorbed by it which can
shorten the distance of card reading. The installation position should be away from the
equipment like motor, transformer and etc, to reduce the effect on the reader.
According to the actual needs, this UHF RFID reader can be with the most suitable
directional antenna with appropriate gain (5.5dBi, 8dBi and etc) to achieve the best
performance.
There are two different interfaces: TTL UART and USB.
