Security is all about layers. When it comes to CNP Fraud, here's an issuer-centric solution just about to hit the market: the Dynamic Security Code from NagraID Security (www.nidsecurity.com). No change at e- & m-merchants. Nothing new for the cardholder to learn. Some minor back-end adjustments for the issuer (or processor). The code on the back of the card changes on its own protecting the data at the source.
