Chipmaker Inside Secure has announced what it claims is “a major technology innovation” that allows mobile operators to retrofit conventional mobile handsets with NFC-enabled SIM cards. The company says its NFC card emulation solution can still achieve industry-standard four centimetre proximity transaction performance. Adding NFC functionality to existing handsets is a great way to rapidly boost the take-up of the technology rather than waiting for users to upgrade to a new NFC handset. The company’s new technology is part of a wider initiative to bring multiple new NFC products to market in 2012 and 2013
