Unfortunately that's only true until the next vulnerability that allows theft via NFC on a mobile device. There has already been one, there will almost certainly be another. http://www.securityweek.com/contactless-visa-cards-vulnerable-fraudulent-foreign-currency-transactions http://www.securityweek.com/contactless-visa-cards-vulnerabl... > "With just a mobile phone we created a PoS terminal that could read a card through a wallet," said Martin Emms, lead researcher on the project. "All the checks are carried out on the card rather than the terminal so at the point of transaction, there is nothing to raise suspicions. By pre-setting the amount you want to transfer, you can bump your mobile against someone’s pocket or swipe your phone over a wallet left on a table and approve a transaction. In our tests, it took less than a second for the transaction to be approved."
