'The chip, called a Memory Spot, is small enough to be attached to a postcard or a photograph and could be used to append video, audio or hundreds of pages of text to all sorts of everyday objects. In hospitals, for example, the chips could allow doctors to add detailed medical records to a patient's plastic wristband.
