This may not be the right place, but Im not sure where is!

For work and home I have 2 "things" attached to my keyring.

One looks like this:

and the other looks like a half size black cigarette.

I think these use RFID but I am a little confused as to the difference between RFID and NFC.

Using an Android phone and an appropriate app, I tried to see if the app would read these devices, but nothing was received.
I used the same apps to read my credit card and oyster card successfully.

I therefore assume they use different technology to the 2 devices I have for door entry.

I am asking for your help as I was wondering if I could put 2 small RFID tags inside my phone case or watch to cut down on the amount of things I have to carry.
I would do this by reading the devices and duplicating the content onto the tags in my phone or watch.

However, now I am confused as to what technology means what and what comes under the NFC umbrella.

Is what I am trying to do even possible?

Thanks
Andrew

Doh, I read that as you were using the phone against some peice of software, not software on the phone. My bad! lol

I guess the specs between the two techs are slightly different. You could always have a crack at writing your own app using the android SDK to see if it isnt an issue with the software filtering stuff?
