RFID (Radio Frequency IDentification) is a technology which allows you to communicate wireless with a small chip/processor that (usually) has no battery of its own. The energy in radiowaves directed at the device is used to power the chip. In practice this means that the distance between a reader and a device must be relatively small (or that you can fry the chip when the radio power is too high).
These chips and devices are simple, passive and can be produced for very low costs.
The first applications were in logistics (tracking and tracing devices) . Nowadays they are used in many professional applications, such as ID-cards (OV-chip), medical environments and so on. All very professional and boring.
And now they have become available for personal use. In a very attractive design and a clever way of packaging called Mir:ror, designed and sold by a small company called Violet.
What the Iphone was for mobile phones is the Mir:ror for RFID. It has become something my wife and children can understand, like and use.
Magnificent, see the website and the video.
