RFID refers to radio frequency identification, which is a non-contact automatic identification technology. It identifies targets and gains relevant data automatically through radio-frequency signals. The RFID system is composed of an RFID reader, RFID antenna, and electronic tag. RFID reader communicates with RFID tag wirelessly through an antenna, which can read and write identification numbers and memory data. The classical custom rfid products includes the control unit, reader antenna, and high-frequency module, namely transmitter and receiver.
1. To learn about which frequency is suitable for your products. RFID readers with different frequencies have different features and applications. For example, low-frequency tags are cheaper than high-frequency tags. They can save energy and penetrate nonmetal objects strongly, best for a moisture-laden object such as fruits. Ultrahigh-frequency tags have vast functions, which can transmit data quickly. But they are power-wasting with weak penetrating power, so there should be less distraction in working areas. They are suited to monitor articles from the seaport to the warehouse. Before making choices, please consult professionals and rfid manufacturers to choose the right RFID reader.
2. Select the most suitable RFID reader. Types and quantities should be determined by the supply method, just like the choices of tags. For instance, to manage the warehouse in-out inventory, the reader could be installed on the hatch door where dock cargos pass in and out. If the products are for special clients, an RFID reader should be installed not only on the hatch door but also on the truck. To control retail shelves, fixed or handheld devices could be adopted for automatic delivery records and counting.
To read and write equipment, please learn about the requirement from the RFID system for the reader, as well as the reader's features. The reader model shall be determined by your location in the supply chain and by the purpose and location of the RFID reader. Selecting the right reader plays a key role in implementing other work successfully. If you buy rfid reader with reasonablethe purchase strategy, then twice as much can be accomplished with half the effort.
The RFID reader can read tag information of different frequencies, filter data, and execute orders as well, so its price is relatively high. Those readers with fewer functions are cheaper. During detailed operation, sometimes several readers will read tag information of the same type. For instance, the simple reader can be used for reading the tag information on the conveyor. However, if the retailer's products come from different suppliers, a multi-function reader shall be used to read the cargo information of different tags.
