Using a 13MHz RFID tag with 30mm diameter the range is 50% greater if I place a 10mm diam neodynium magnet against the back of the tag. It reads and writes fine. i stumbled over this thread today while i played around with my new MFRC522 RFID Reader. My intention was, to be able to read the rfid-cards through my door.

All RFID readers have the ability to control how much power they send through the cables to the antennas. Check your reader’s settings to see how much transmit power you are transmitting (in dB); the higher the number, the more you'll increase read range, and vice-versa.
There's not too much you can do to increase range, other than to add a larger loop antenna. The RFID chip is powered by rectifying the rf signal transmitted by the reader, which induces a current in the card's loop antenna.
How can I increase the read range of RFID tags? You can improve the read range by selecting the right tag type, optimizing the tag’s placement and orientation, and using enhanced antennas and readers.Sep 11, 2008. Range Rfid. In summary, The conversation is about extending the range of a proximity RFID tag to eliminate the need to physically walk up to the reader. The idea is to build a small micropower transmitter that can broadcast the tag information, allowing for the gate to be opened by driving up to it.
All you need is a high gain antenna on top of the car and the ability to steer it directly towards the reader. If it's a multi element Yagi should do the trick pretty well. First step would be to work out which RFID band the card is operating in. I have a question about the Parallax Serial RFID Card Reader. Is there a way to increase the range at which it can read tags? Maybe with a bigger antenna or more power? A maximum distance of 20cm is a little short for my project. The read range of RFID tags can be influenced by factors such as the frequency band, the power output of the reader, the sensitivity of the tag’s antenna, and environmental conditions. Understanding these factors is crucial for selecting the appropriate RFID technology and optimizing the read range for specific applications.
I think i found a happy medium in a 15.6mm X 6mm 215 tag, which I plan on setting in a resin ring. I still need to either remove some of the wood to shorten the distance or increase its range. I know where the antenna on the pcb is, but unsure how to add/replace it.
