Multi-Frequency RFID reader.

Well I want to create a security system for my home that can read/write RFID tags of multiple frequencies. The more the frequencies that the reader/writer can use the better for me. I have searched around and came up with sky RFID which had many reader/writers, but not something interesting . I want to use 1 machine so that the cost and space is reduced. Any ideas of where I can find such RFID reader/writer? (The frequencies I want it to read are- but not limited to - 125/134.2kHz & 13.56 MHz and probably if not hard- 865 … 868 MHz and 865.6 … 867.6 MHz and generally any other frequency widely used by RFID industry) I hope you understand the message above , please reply with any piece of information.

Sounds expensive and not single-chip.

I can afford paying any amount of money!

Well I personally use this

It has been a great unit. Excellent and repeatable range. And works with my chips. I would call up the guys at sky and alientech and get their opinion. Sorry, I don’t feel like doing the legwork for ya right now.

It has only 1 protocol, I at least need the most popular ones of the ECP... and maybe some more...

Don’t forget that each frequency that you want to work with is going to take a different tuned antenna too.

so… their going to be like 3 antenas, for the most popular frequencies used, 13Mhz and 125khz-134Khz

Kindly, irrelevant, but for different protocols do I need different chips or just program?

I couldn’t find the products they were talking about.

thx dude, I already ordered what I wanted, for like 400$, I thought I could find something cheaper but I didn’t … anyways thx everybody.

Just out of curiosity, why do you want to spec your system like this? No one that I know of does this because they design their system with a given tag protocol then go with it. If you had to pick a protocol why not just find one that works well and go with that?

I dunno, just sounds like you’re spec’ing your security system strangely.

Sounds like what he is really after is a way to read what ever card he comes across. This would be really handy for someone wanting to gain access to something by spoofing a known card.
