Where the banking sector used to be a sort of solitair developer of bespoke applications, we can increasingly see technologies and applications from other industries being used. One example is the mobile operators billing technology that is now being used by ING for billing their payments. Another example lies in money laundering detection.
Neteconomy for example is a company that started out detecting false/fraudulent phone calls, to discover that its technology is also useful for banks. This press release contains a testimonial by Nationwide Building Society to that effect.
