Confirm the working frequency and communication protocol: RFID readers can be divided into low frequency, high frequency and ultra-high frequency according to the working frequency, and different types of readers are suitable for different application scenarios. At the same time, different RFID systems may adopt different communication protocols, so it is necessary to confirm the required working frequency and communication protocol when selecting the type.
Confirm reading and writing distance and recognition speed: Reading and writing distance and recognition speed are important performance indexes of RFID readers, which directly affect the recognition effect and efficiency of RFID system. In the selection, it is necessary to confirm the required reading and writing distance and recognition speed according to the actual needs, and choose a reader with stable performance.
Confirm the protection level and working environment: The working environment of RFID readers may be harsh, such as outdoor, damp, high temperature, etc., so it is necessary to choose readers with corresponding protection levels to ensure their normal work and service life.
Confirm the interface type and communication mode: RFID readers need to communicate with computers or other devices, so they need to confirm the required interface type and communication mode, such as RS232, USB, TCP/IP, and select the corresponding reader.
Confirm the price and cost performance: the price of RFID readers is quite different and needs to be selected according to the actual demand and budget. When comparing prices, we need to consider the value and cost performance of the reader itself, and choose the product with higher price.
