Below is a link to a company called txtchq which has developed a SMS based money transfer system.
The company is testing the concept using virtual cash (so no bank or credit card details are needed) and, similar to the free share issues of the internet/dot com boom, is giving away shares as part of this exercise.
Also, you can gain extra shares through referring people.
It uses long mobile numbers so NO PREMIUM RATES at all!
Apparently this is a very effective micro payments system so if you are a web designer or hoster then it is worth looking at.
I very much like the idea and concept and would like other views.
