Apple is developing technology called “iKey”, which will allow users to simply tap in a sequence of numbers before waving the over an RFID device fitted beside the door to open it.

The tech giant has recently filed for patent that has lead to many technology analysts to believe that the upcoming 4G iPhone will incorporate the iKey feature.

The patent application states: “The device can communicate with an external device to open a lock. By way of example, the electronic device may be a model of an iPhone.

“The external device may be any suitable electronic device such as a portable media player, personal data assistant or electronic lock that may be used to access a door, car, house or other physical area.”

A spokesman for Apple refused to comment on the patent.

Leander Kahney, a consumer technology expert said that there are strong rumours that Apple had already been testing the technology and it could lead to the company even trying to replace consumers’ wallets. 

The technology would work by having users entering a PIN code on on their 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 same technology could also be used on cars.  Car manufacturers, including Mercedes, Lexus and Toyota, are also starting to use keyless entry systems for their vehicles.  The iKey would not only your unlock your car, but could also be used to start the engine.
