No i do not think that smart phones would become a digital because there is many reasons why its not a good idea. The first reason is your personal business on your phone like your credit card information. If you just so happen to loose that cell phone one day someone else would be able to access that information if they find it.
NFC should not be supported because its not just credit cards that people hold in their wallets, sometimes people hold their social security card in their wallets, and their insurance card and things of that nature. So if NFC were to be put into action what would people do with the rest of their personal things. They would then have to carry around a wallet and a cell phone that holds their credit cards. So there would be no use in both when you could just have the wallet that holds everything.
Some people may think that its a good idea because it cuts out the hassel of looking for credit cards and things but its not that much of and advantage. People would just have to think ahead and think that the NFC is really not good to use because of all the disadvantages it has. Its a good idea overall but its just some faults that need attention.
