Point-of-sale location sensing...

Following on from my previous posts about electronic receipts and follow-up texts, it occurs to me that location sensing is inherent in using an electronic point of sale (EPOS).

All EPOS units are uniquely identified and known to the financial transaction network. Hence, whenever we buy something, our location could be precisely determined, even indoors (especially indoors). Thus any follow-up information sent to our mobiles could be made location specific with a high degree of accuracy.

Using the same principle of known fixed EPOS position, it therefore seems a useful idea to add a location stamp to any electronic receipt that we might be able to download into our mobile devices.
