Using geolocation and photochallenge, you emulate a loyalty card. And you make it social.

1. For instance, a coffee-shop proposes a photochallenge about itself (point of sales, dishes, drinks, design,...).

2. At each visit, customers take the picture required, which is validated by geolocation.

3. After 6 visits (6 pictures), customers earn a voucher, and share the photo mashup.

4. Summary: customers came and consumed 6 times, took pictures they shared to their audience, all this for a small reward.
