You can even have one for both, as you can combine RFID events. Have a
blue wand for check in, red one for checkout. Red wand, then book,
checks the book in.
Multiple RFID events makes me wonder, how many different RFIDs do you
need to allow text input by waving different objects? I'm thinking the
answer is three, as three objects can make 3^3 combinations, enough
for the letters and a space... This could come in useful if one used
Nabaztag to Twitter with.
