How Far Can a Microchip Be Scanned? Understanding RFID Range
Discover the scanning range of microchips, from passive to active RFID tags, and learn how they function in various conditions.
0 views
The scanning range of a microchip varies greatly depending on the type of chip and the reader's power. Passive microchips are typically scanned from a few centimeters to a meter, while active RFID tags, which have their own power source, can be scanned from several meters to over 100 meters in optimal conditions.
FAQs & Answers
- What is the difference between passive and active RFID tags? Passive RFID tags do not have a power source and rely on the reader for energy, while active RFID tags have their own power supply and can transmit information over longer distances.
- What factors affect the scanning range of microchips? The scanning range can be influenced by the type of microchip, the power of the reader, environmental conditions, and physical obstructions between the chip and reader.
- Can microchips be scanned through obstacles? Microchips typically have reduced scanning ranges when obstacles are present; passive chips may be significantly hindered, while active chips can sometimes maintain better performance.
