[citation][nom]bobusboy[/nom]I personally have zero desire to surrender physical currency in favour of digitized forms to complete transactions. Debit and Credit cards are more than enough for me.NFC is not a technology I will used unless forced to; to complete transactions.[/citation]
Going NFC isn't going to get rid of physical currency. If you look at cities like Seoul, Tokyo, Hong Kong, etc who have widely adopted NFC/mobile payment methods, nothing changed except efficiency.
When I visited Seoul, I bought a bus pass like a total noob tourist. When I was riding the bus to my destination, I saw people just bump their butt or bag next to the machine in the bus and it beeped. They didn't even take out their phone to pay with NFC. That is how much mobile payment methods matured in other countries. They don't think twice about it.
Sorry, but there is no way I trust any type of 'wallet' in my -hackable- devices.
Let's face it, this is stil the Wild West out there in Cyberland and no Wyatt Earp or Clint Eastwood type Lawman in sight.
