From the website :Neuhausen fuer Neuhauser.

Local shops and services in Neuhausen have got together in order to show the variety of what this area of Munich has to offer.

The NeuhausenCard is an advantages card where you can:
*obtain a reduction
*get a special service

Participating businesses will have the red NeuhausenCard sticker in the windows/at the entrances.

You can find a list of all participating places here.
e.g. Galerie Kaufhof, several chemists, clothes shops, hairdressers, pubs, bakeries, opticians, shoe shops and more.

The website doesn't say how to obtain the card itself, but I would think that any of the participating shops would know. Let us know if you've used this before!
