Apple is bringing wireless charging to future devices according to patents

On Aug 28, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals electronic devices such as an iWatch with wireless charging circuitry. The news of Apple’s future iWatch possibly offering wireless charging first surfaced in June. According to the patent filing, Apple’s future iWatch will be able to work with wireless payment system at retailers and one day even open security doors of one sort or another like a hotel room, an office door or your car door. The new wireless circuitry will also one day extend to a wide variety of devices including the MacBook Pro, iPad and beyond. Whether this patent pending wireless chagrining circuitry will make it into Apple’s first wearable device expected to launch in September is unknown at this time. Electronic devices often include batteries. A battery in an electronic device can often be charged by using a cable to couple the electronic device to a source of power. It is not always convenient to rely on wired charging arrangements such as these. In compact and portable devices, for example, the use of a charging cable may be unwieldy. Charging cables can be avoided by using wireless charging, but wireless charging circuitry can be bulky.
