rfid triangulation

In the actual application, when we get a UHF label, often want to know the capacity of its various storage area is how much, especially programmers do the program, it must know what the chip, some characteristics, in order to do a better service for the program, not blind, Otherwise, the development of the program may cause a variety of unforeseen problems. So how do we know what the label is in the hands of the brand, what chip? Here's how to tell us how to identify the UHF label chip model.UHF

Brief answer:The reasons for the diversification of RFID standards are briefly introduced:It is caused by different technical factors and benefit factors: The operating frequency is distributed in multiple frequency bands of low-frequency to microwave, with different frequencies and large technical differences. The difference of the range of action leads to different standards: the transponder is divided into active and passive modes of opera

The basic working principle of RFID technology is not complex: After a Tag enters the magnetic field, it receives the RF signal from the interpreter and sends the Passive Tag of the product information stored in the chip based on the energy obtained by the induction current, passive or passive tags), or actively send signals of a certain frequency Active tags, Active tags or Active tags); the interpreter reads and decodes the information, to the centr

A future credit card designed by Jacob to display the consumption ratio Security Features of fingerprint recognition, and display transaction records A major reason for credit card flooding attacks is that consumers do not know how many injuries they have when swiping their cards, you must wait until you go to the ATM, online bank, or even the bank sends a bill to know that the blood has been lost.But recently a Swedish young designer Jacob? Jacob Palmborg has designed a credit card for future

as an example. Generally, an encryption algorithm is used to generate a unique card password based on the unique ID of the key and card. When reading a card, read the card ID, generate a card password based on the algorithm and key, and then use the password to read the card content or even write the card. The PSAM card is essentially a single-chip program and E2PROM file system. If you do not use the PSAM card, you can also use software to implement this process. Although the implementati
