Not sure when it happened but Google launched a new beta version of its Google Maps for Mobiles with a feature “My Location”. This feature allows you to see your approximate location on a map via a mobile phone without using GPS. It calculates your location based on the nearest phone towers. Its nothing new but its exciting that the technology is starting to get used some more. While the Google thing works on many platforms, the Java integration of this technology is under JSR-179 “Location API” and there is a pretty cool article about the Java Location API here. This is just the beginning! This technology over the next year is going to get so hot!! Imagine the advertising potential as well as the opportunity for new and exciting business ideas around social computing etc.. How exciting.

This is great (and maybe even not that new). My long thoughts of unique and expiring credit card details to be used for transactions to eliminate post-transaction fraud seems to have come true – at least online;

“…purchases on-line using my card and a bit of software
called Shopsafe which produces one-time cards with a specified
expiration date and a specified credit limit.”

Now lets see when we can have this for offline transactions as well – I am thinking of a physical “security key with changing passwords”-like concept with small LCD screens on our credit cards.
