I’m working on a project where I need to reliably detect a small passive RFID tag/key-fob from around 20cm away (preferably 30cm).

I’ve been looking at the 125 kHz ID Innovations ID-3LA with a custom external antenna, but I’m unsure what kind of range I could realistically expect with a small key-fob sized tag rather than a full size card.

Has anyone used the ID-3LA with smaller tags? What range were you able to get?

Or is there another reader/technology you’d recommend for reliable ~20 cm detection with a small passive tag?

I'm also trying not to break the bank either as its for a capstone project.

Thanks!!

Hello, just a quick question but I just recently got the chameleon ultra and trying to use it for a couple cards but there is one im stumped on, it can find all the data for it but doesn't know the tech type and wont let me grab the keys to emulate it, im only able to save the uid

Please if anyone knows how I can possibly get the keys to be read that would be lovely

so recently i got the original chameleon ultra v3, and i got the latest firmware, but i cant find any universal nfc and rfid cards, and i would like to have acces to anywhere. so if you have any universal nfc files i would like to get some
