Is it the best solution for access control?
Unlocking using RFID tag is becoming an increasingly popular way for accessing or unlocking special rooms. In other words, RFID tag functions as a key and it is most commonly used in access control or opening electronic locks. Its dimensions make it very practical; it is also waterproof and long lasting. People usually carry it as a key ring or a replacement for RFID card.
Each tag has own unique serial number within its contactless chip.
We can say that the forerunner of modern RFID devices is a covert listening device more popularly known as a bug or wire that sends signals over radio waves. Modern RFID tags operate at frequencies of 125 KHz and 13.56 MHz.
