wireless Mini

Hi!

What would be the smallest solution to get a wireless connection to an arduino mini board? I only need to send/receive a few bits over a very short distance (<10cm).

thanks

Infrared?

Hmm, good idea. Has anyone done an Irda connection with Arduino? Should simply be software serial or am I wrong?
