Dual Frequency Reader

My original plan when I got my NExT chip was to put it in my left hand and clone my work badge onto it. I’ve got a simple card duplicator that works on the low frequency stuff and I’ve cloned my badge to a key fob successfully. The only concern I have is when I brought the RFID diagnostic card to work it kept flashing between both high and low frequency. I believe the reader they’re using is this one. “https://www.rfideas.com/products/readers/pcprox-plus“ and all it does is type in a number and hit enter on our punch clock system (it doesn’t have a keyboard otherwise I’d just type it myself) what I’m getting at is will having the high frequency chip there at the same time be a problem when I try to scan?

Side note, I’m totally new to the scene and little to no knowledge of the terminology so be easy on me please.

Yeah, that can be an issue. There’s no real good way of fixing it right now. Some people have found out ways to hold your hand a certain way but it depends from reader to reader.

When you purchased your NExT you should have recieved 2 x xLED field testers. ( 1 x 125kHz 1 x 13.56MHz )

you could try using each of these to find the location and orientation of the sweet spot (xLED at its brightest) and then present your NExT accordingly…Just a thought. Good luck

That is a good idea, I only brought the 125khz one in because that’s all I was thinking about needing but I suppose if I bring both in I could find the sweet spot for each coil in the reader.

@Pilgrimsmaster Thanks for the idea, I went in with both of the xLED’s and found that it’s going to be really easy to get the LF side of my chip to scan first. In fact finding a spot for the HF side proved to be a pain which works out great in my case.


Great stuff
