You know, in Europe their physical credit cards use the embedded chip AND require a PIN - significantly reducing fraud. In the US, most replacement cards are implementing the chip, but not with a PIN requirement, minimizing the reduction of fraud. When you use these electronic payment systems, Android Pay, Apple Pay, etc, there is built in security that exceeds the even physical card with chip PIN used in Europe. Credit card numbers do not electronically get passed to the vendor; the recent hacking of Target, Home Depot and Jimmie John's to name a few would not of been as severe if these NFC based pay systems were used, as these stores would not have any credit card numbers to be 'stolen'. In addition, these electronic payment systems change the 3-digit code on the back of all our cards for each transaction, therefore no transaction could ever be duplicated from a store purchase. We are, however, very dependant on the security of our information with the security of Apple, Google, etc., as well as the tracking of that still important marketing data they will be compiling. The use of secure fingerprint, passcode, password only enhances your security, and IMHO, worth it.
