Can RFID measure speed?
Yes. Good RFID in HF/UHF range readers can read in 200 kph and with clear environment it can go up to 250 kph; With the specially enhanced power in readers, it can detect objects moving between 800–900 kph too. Reading speed purely based on the power of reader. Having active tag, will also increase the speed level.
Can RFID tags be read through metal?
Radio waves bounce off metal, so it is impossible to read a radio frequency identification tag placed within a metal box.
How do RFID tags affect the speed of reading?
When you read an RFID tag, data is transferred between tag and reader. RFID frequencies affect the maximum transfer speed. Higher frequency means you can read more tags faster. If you have only one tag to read then this isn’t important. But if you have hundreds to read at the ‘same time’ and if the tags are moving, this can be very important.
How to choose the right RFID reader for your application?
Type – High-performance readers are a necessity in high speed applications because they have faster processing and performance. Key Takeaway: Choose an RFID reader with the ability to process at least 500+ tag reads per second. IP Rating – After surveying the environment, does the reader need to be weather resistant?
What are the advantages of RFID handhelds?
In contrast, with an RFID handheld, you do not need a direct line of sight and it is possible to get a good reading even if the transponder is obscured or the light conditions are not optimal. You can also be further away from the item being read and have the capability to read in excess of 300 tags per second.
Do you need a direct line of sight to read RFID?
You also need to be within a short read distance and directly in front of the barcode to allow the 2D scanner to accurately decipher the code. In contrast, with an RFID handheld, you do not need a direct line of sight and it is possible to get a good reading even if the transponder is obscured or the light conditions are not optimal.
