Siteminis pulled together a site for Urban Planet mobile that handles transactions re-occuring on a monthly basis for customers, here's how it works:

Phase I

Travelers go to http://www.travelingo.com on their mobile phone and sign up for a free trial, they then have 7 full days to travel and let their mobile phone
speak the language for them for emergencies, restaurants, hotel, greetings, and needed phrases - in 10 languages.

Once they have passed the 7 day trial period they are charged a small fee of 4.95 per month on a card that is entered into the site, with PCI compliance, and full
security, giving them access to the site at anytime in the future.

Phase II

Travelers will be able to engage with the mobile site by typing in a phrase and have it translated back in over 25 languages, not only seeing the translation but
hearing it as well, allowing travelers to hold their phone up with the speaker on and let anyone anywhere hear the translation - fixing any faux pau that may happen
while trying to read the language.
