Here is the killer SmartCard application

OK, we all have our SmartCards with a fully functional banker bot. Now, government pays you a dollar if you tap your card on the government Icon on your browser. What happens? Instantly the entire statistics of the US economy is known to three significant digits.  GDP, prices, rates, unemployment; all localized to your vicinity or aggregated up to the national level. Everything the 100 trillion dollar derivative industry wants to know is instantly available to anyone. We have yet to even get close to the full potential of putting a banker bot in everyone's pocket.
