The difference between LF,HF and UHF RFID tags and features

Low frequency (LF) and high frequency (HF): Low frequency (LF) and high frequency (HF) bands RFID tags generally use the principle of electromagnetic coupling The high frequency typical operating frequency is 13.56 MHz. The RF tag in this band, because its working principle is exactly the same as the low-frequency tag, that is, it works by inductive coupling, so it should be classified as a low-frequency tag. On the other hand, according to the general division of the radio frequency, its operating frequency band is also called [...]

Mifare 1k UID number format

Each Mifare 1k has unique number (UID number). But you will find different UID number read by differen readers because the UID number of MIFARE 1K card has multiple international standard encoding rules. Some NIC card numbers read by the card reader will be repeated, mostly because the card is not read according to the international coding rules. For example, the data of the 0th block of the 0th sector: 2A83155E E288040047C129D24D000607 Manchester code (hex): HEX big endian 1. The positive code is “2A83155E”, which is [...]
