Using Arduino + RFID to Email when something is removed from a box?

Hey everyone,

I'm looking at completing a home project using an Arduino and any help as to how to approach this or where to look would be really appreciated!

Essentially I want a box filled with a number of items with RFID tags and I want the system to send an email telling me if an item has been removed (and preferably which). I'm pretty new to this, but I have a feeling I have seen similar projects around. Can this be done and if so can anybody help me?

EDIT: I understand this may not be possible with RFID, but if so is there a different way of wirelessly checking (say once a day) if all items are present or not?

Thanks!
