Humble mobile phone. Used to be a communications equipment has rapidly developed into a portable entertainment device, and an important tool for work and entertainment. For this reason, many people panic, if you are not careful to stay at home call. Separation anxiety might be worsening in the future with Apple’s iPhone patent means that the company hopes to replace the house and car keys and wallet, which makes it even more indispensable.

The so-called “key ‘technology, the user’s PIN code input devices (like iPhone) using the rotary lock combination that is next to an electronic pad to open the door to fly. This system is based on Near Field Communication (NFC) is called the new technology — a short-range high frequency wireless communication technology is used to allow the use of mobile phones, the main exchange of data between devices by 10 centimeters (about 4 inches) distance.

NFC technology is a simple extension of the ISO / IEC 14443 standards for contactless cards and proximity card into a device on the smart card and RFID reader interface device. An NFC device can with the existing ISO / IEC 14443 smart cards and readers, as well as with other NFC devices, so with the existing infrastructure is compatible with non-contact has been in the public transport and many people use the payment system. This means that key equipment can also be used as an electronic wallet.

Apple iPhone display, as a device, which key examples of the technology used, but the patent also says: “external devices, such as portable media players, personal data assistants, or any other appropriate electronic lock electronic devices can be used for Access doors, cars, family, or physics. “keys can also be used to lock or unlock the device to transfer data between computers and technology.

Many car manufacturers, including Mercedes-Benz, Lexus, Toyota has already begun for their vehicles do not enter the system through installation of key chains, as well as many global public transportation systems that use or are being implemented in the system of contactless card entry. Therefore, these systems may use the equipment Key would not be so difficult to implement. Home and office, it should be with the existing electronic, computer-controlled lock lock replacement.

In the “key” is the second patent refers to the National Assembly. The former is presented in November 2009 a detailed application procedures, data transmission known as the “Grab & go” goal is to make the data transmission between devices with different types of play time. It was suggested that, in these the NFC can be used to connect high-speed before the start of data, such as 802.11x standard 3G, HSDPA or Bluetooth, the devices of communication channels.

There is speculation that the next iPhone 4G technology, the ability to include key, but Apple is likely to face a difficult task to convince some people believe that digital devices, all the keys, the money likely to be lost – even if the patent that any transfer of information between devices encryption.

And how when the battery died? It can be misleading, but my key instead of the current portfolio of power to end. However, I believe that no one is willing to go the lack of technical keys.
