While in Singapore I was surprised by their level of wireless integration into everyday life. The most impressive was in automobiles. With a simple debit based device on the dashboard you could enter into a parking lot and pay automatically. It seems that this integration was driven by the ERP (Electronic Road Pricing); a tolling system that is everywhere in Singapore.
When I was asking a taxi driver about it, he did not seem nearly as enthusiastic as I was. He scoffed and said “ERP … PAH! … Everyday Robbing People”.
LOL. The downside of the ability to take a payment anywhere is that governments will.
