extend rfid card range I am using the Addicore RFID library and have successfully set up a working sketch, now however I have come across a problem. The RFID reader can't read through the 3cm of wood I want it to read through, and I therefore try to increase the range of it.

You can get active RFID cards but then you risk the higher probability of them being skimmed. The better alternative for gates would be to switch to a Transcore tag system. It should tie right .
Here are some things I've considered: Ditch the embedded antenna on the cheap RFID reader and construct my own, larger antenna. I'd need to see if the onboard MFRC522 is up to the task of providing additional power. Look for a different IC around which to build a reader . You can get active RFID cards but then you risk the higher probability of them being skimmed. The better alternative for gates would be to switch to a Transcore tag system. It should tie right into your existing Access Control system, the tags can stick to the windshield or be mounted to a license plate. Reply. Tldr: how can I add an external antenna to an existing nfc/rfid reader to extend its read-range? I got a cheap Amazon smart cabinet lock that works with just about any nfc tag/rfid tag i put in front of it, as long as I set that type of tag/chip as the control card.
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 am using the Addicore RFID library and have successfully set up a working sketch, now however I have come across a problem. The RFID reader can't read through the 3cm of wood I want it to read through, and I therefore try to increase the range of it. 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. Therefore i wanted to extend the range of the reader. I had success by placing a .

Closer ranges, like 2cm, the angle and position are not so sensitive. Hope this helps. The range of a RFID reader with a (round) coil with diameter D is approximately D/sqrt(2). So you need a (round) coil with approximativ D=15cm to get more than 10cm reading distance. But as the inductance needs to be the same, you have to reduce the winding turns of the coil accordingly.This week's pentestip is a hands-on how-to with the RFID Antenna Extender.Manufactured by Lab401, these devices are world-first: passively boost read/write/c.
One way would be to boost the reader antenna’s power output. But most countries place limits on the amount of RF energy that devices can emit—for health reasons, and to prevent them from interfering with other devices. Another way would be to increase the tag antenna’s size. You can get active RFID cards but then you risk the higher probability of them being skimmed.
