Some people say that all technology serves only one purpose: procreation. Well in this case it’s also a workaround for some cultural and religious taboos (by Markus Kison):

The CharmingBurka deals with Freud’s idea, that all clothes can be positioned between appeal and shame. I decided for the Burka, because this cloth is positioned on the very side of shame and add a digital layer to it. With this layer women can decide on their own, where they want to position themselves virtually. This means that the Burka is sending a picture, which the wearer has chosen, via Bluetooth. Every person next to her can receive her picture on his mobile and that way see her self-determined identity. The virtual appeals can not be gathered by the laws of the Koran.

Therefore the Burka is equipped with a bluetooth antenna, micro-controller and uses the OBEX protocol, already working with most mobile phones.
