Free software can be "free as in beer" (i.e. no cost) or "free as in speech" (i.e. open source), or both. The Nelso Prague app takes this literally - it provides actual free beer.
The latest update to the Prague app (download link), contains three Passbook coupons for restaurants in Prague, one of which (Hergetova Cihelna) was the site of the second PragueCrunch meetup. These coupons entitle the bearer to a free beer, no purchase required, or a glass of prosecco.
We're doing this as a test of the appeal of Passbook to travelers - so if you're in Prague, download the app and have a free beer on us.
