INTRODUCTION TO RFID
LF (Low Frequency) RFID Standards and Frequencies
In the LF (Low Frequency) band, we have passive RFID tags that work at around 125 kHz and 134 kHz according to magnetic coupling principles.
LF RFID tags – Common advantages :
- Used all round the world.
- Work well in proximity of liquids and metals.
LF RFID tags – Common disadvantages:
- Very short read ranges (a few centimeters) that limit their use in several applications.
- Limited quantity of memory and often read-only.
- No multiple readings.
- Higher production costs in comparison to other passive tags.
LF RFID tags – Common applications:
- Animal tracking.
- Access control.
- Integration into car key-fob.
- Applications in environments with a high presence of liquids and metals.
