UHF RFID Electronic Tags

UHF RFID electronic tags usually refer to electronic tags that conform to the ISO18000-6C & EPC C1G2 protocol. Of course, there are also electronic tags of the ISO18000-6B protocol, but the ISO18000-6B protocol is gradually marginalized. First, what needs to be considered is the storage structure of UHF electronic tags ? 1. What is the model of the chip? 2. What is the memory map of the chip in the chip's specification? Generally, the electronic label of the 6C protocol is divided into a TID area, an EPC area, a user area, and a reserved area. The TID is the serial number of the solidified chip and cannot be changed. The EPC area is the most frequently used and written area. Some tags have a user area, and some tags, except for the user area, are usually reserved for storing access passwords. What kind of data do we need to store in UHF RFID electronic tags? Does the data need to be encrypted? A typical case is the coding method used in

Indian Company Simplifies Solid Waste Management with RFID Tags

Indian company Agra Nagar Nigam has decided to simplify solid waste management by installing RFID tags, which are installed in 99,450 houses in 51 communities and handing over 350 RFID handheld readers to cleaners. Homeowners must put dry garbage and wet garbage in different bins and pay a Rs 65 management fee each month. When the cleaner collects garbage from the house and scans the RFID tag installed in the house, it will automatically signal to the command and control center of the Agra Smart City Office. After collecting garbage, the homeowner will receive a text message from the mobile phone. If cleaners do not collect garbage at home, homeowners can also complain through mobile apps. Homeowners must keep the RFID tags intact. If there is a problem with the label, the homeowner will pay a fine of Rs 100 for this. The collected garbage will be sent to six collection centers located at different locations in the city. The dry waste is then sent

What is the difference between a barcode and an RFID tag? What are the types of RFID tags?

Bar codes and RFID tags are both item information identification technologies, and their essence is to give a special number to an item, through which you can get information about the item. The bar code is numbered by knowing the change of the image by optical means. The RFID tag can be considered as the electronic version of the barcode, and its working principle is the radio principle. The number information in the RFID tag chip is obtained through the process of electromagnetic wave carrier and modulation. RFID tag category: Low-frequency electronic tags : Its operating frequency range is 30kHz ~ 300kHz. Typical operating frequencies are: 125KHz, 133KHz (There are other frequencies close to it, such as TI uses 134.2KHz). High and medium frequency electronic tags: The working frequency of mid-to-high frequency electronic tags is generally 3MHz ~ 30MHz. Typical operating frequency is 13.56MHz. UHF and microwave tags: Ultra-high freque
