Travel Trends - 2-D Barcodes, TripIt, Ricoh 500SE

Smartpox - Create a 'pox' (2-d barcode, see the image above) with any information you like...restaurant review, link to a song, scavenger hunt clue...and stick it on a sign, wall, anywhere. Then, when users see your barcode, they can take a picture of it with their cell phone and download the review or song. Pretty much any type of text-based information can be contained in the barcode.

Semapedia.org - Using the same technology as Smartpox, Semapedia.org is a non-profit, community-driven project that allows users to create and distribute Semapedia-Tags (again, think barcodes) that link to the free online encyclopedia Wikipedia. So, for example, you could be walking past Chase Field, see a 'barcode' and take a picture of it with your cell phone. Your phone would then pull up the Wikipedia page about Chase Field, telling you everything you need to know about the stadium.

TripIt - A new travel site from Hotwire co-founder Gregg Brockway, TripIt wants to help users keep all of their travel-related materials in one place, regardless of where they book online. Once a user enters a flight reservation (for example), TripIt will automatically add basic info for your trip (maps, weather, directions) as well as allow you to share the info with friends, family, etc...plus, the service is aiming to be widely accessible via the web, mobile or in your calendar.
