How do you choose the right reader/writer?
1. Consider application: The requirements of various industries and application situations may differ. For example, warehouse logistics necessitates long-distance reading capability and high-speed tags recognition, but the retail business places a greater focus on readers’ group reading ability and adaptability to various contexts. As a result, while selecting readers and antennas, it is critical to carefully analyze the application and needs.
2. Frequency Selection: Different frequency bands have unique advantages. LF is appropriate for close range reading and small-scale item management, while HF is useful for financial payment and security applications, and UHF is appropriate for large-scale item tracking and supply chain management. Determine the optimum frequency depending on the specific application needs.
3. Reading and writing distance and speed: There are also differences in reading and writing distance and speed between different combinations of readers and antennas. To guarantee coverage and read/write speed meet requirements, choose the suitable reader/writer power and antenna type according on your specific needs.
4. Anti interference: In some complex environments, such as factories, warehouses, etc., there may be interference from high-intensity electromagnetic fields or other wireless signals, or interference from metal shielding and moisture. Therefore, it is necessary to purchase readers and antennas with good anti-interference performance.
It is a four port UHF RFID fixed reader, which embeds the M2240 module. Its communication interfaces can be USB, RS485, RS232, and 100M Ethernet, etc.. It has four TNC antennae interfaces. Aluminium alloy of the whole body makes this reader more rugged and durable as well as the excellent heat dissipation capability,
IP65 protection grade, soft and hard plastic double injection molding finish, making the product waterproof, dustproof, anti-corrosion, anti-oil
It is a high-end medium distance integration UHF RFID reader and product. Its design is equipped with our UHF M2210 read-write module and 6dBi circularly polarized antenna, and the main chip is selected by the new generation of high-performance ARM-COTEXM3 processor.
High frequency card reader is a card reader that works in the high frequency HF band. It generally works in the 13.56M frequency band. Sensors at this frequency no longer need coils to be wound, and antennas can be made by etching them alive and printing them.
High frequency card reader is a card reader that works in the high frequency HF band. It generally works in the 13.56M frequency band. Sensors at this frequency no longer need coils to be wound, and antennas can be made by etching them alive and printing them. Inductor usually works by load modulation, that is, the voltage on the antenna of reader is changed by the switch on and off of the load resistor on the inductor, so as to realize the amplitude modulation of the antenna voltage by the remote inductor.
Low-frequency RFID systems use ID cards, known as Identification Cards, as their electronic tags. ID card is a kind of induction card that can not be written, its internal only stored data is a fixed ID card number, its record content (card number) is written by chip manufacturers before sealing card factory, sealing card can not be changed, developers can only read card number to be used. ID card and we use magnetic card normally same, used only “the number of card” just, besides card number inside card, without any confidential function, its “card number” is open, bare.
