Hi! First poster here...

I am about to start a project which requires reading rfid (passive) from 1-meter distance.

My questions are:

- I am planning to use UNO, which seems powerful enough, since no complex computations will be made. Is there something I am missing here?

- It seems that for a passive rfid the 1 meter distance is quite a lot. Has anyone any ideas? In my prior research I found that higher frequencies may work in such a range...But I got totally confused about the direction I should follow...Maybe I should mod an already existing rfid shield to increase its range...

- My budget is around 50-70euros, for the arduino, the shield and 2-3 rfid tags. How does it sounds?


Note: I am an arduino noob (I've played with an arduino 2-3 times)  but quite experienced with programming.

Thanks!

The UNO will be sufficient, given the right kind of RFID reader.

It is. Passive RFID is usually only a centimeter or so. Active RFID is used for longer ranges (but costs a lot more).
