Wi-Fi memory chip.
Stick the minute memory chip anywhere! Imagine sticking a grain-sized memory device that can carry and transmit information at high speed, anywhere onto your wristband. A very tiny memory device is developed by the 'memory Spot’ team at HP Labs which is of the size of a grain of rice or even smaller (2mm to 4MM). This miniature wireless data chip could provide broad access to digital content in the physical world. The chip incorporates a built-in antenna and is completely self-contained, with no need for a battery or external electronics. The chip has a ten megabits-per-second data transfer rate that is ten times faster than Bluetooth wireless technology, and is comparable to Wi-Fi speeds. This effectively gives us instant retrieval of information in audio, video, photo or document form. With a storage capacity ranging from 256 kilobits to four megabits in working prototypes, it could store a very short video clip, several images, or even dozens of pages of text. Future versions may have larger capacities.
