pple’s iKey would see your keys and wallet replaced by an iPhone or similar device.The humble mobile phone. What started out as a communication device has quickly evolved to become a take anywhere entertainment apparatus and essential tool for work and play. So much so that many people feel panic-stricken if they accidentally leave their phone at home. Such separation anxiety could be even worse in the future with a patent filed by Apple suggesting that the company wants the iPhone to replace your house and car keys and wallet, thereby making it even more indispensable. Nicknamed “iKey” the technology would see users entering a PIN code on the device (such as an iPhone) using an onscreen rotating combination lock and waving it over an electronic pad located beside a door to open it. The system relies on a new technology called Near Field Communication (NFC) – a short-range high frequency wireless communication technology primarily aimed at usage in mobile phones which enables the exchange of data between devices over about a 10 centimeter (around 4 inches) distance. The NFC technology is a simple extension of the ISO/IEC 14443 proximity-card standard found in contactless card and RFID devices that combines the interface of a smartcard and a reader into a single device. An NFC device can communicate with both existing ISO/IEC 14443 smartcards and readers, as well as with other NFC devices, and is therefore compatible with existing contactless infrastructure already in use for many public transportation and payment systems.
