  • IBM has also developed another personal RFID device, this time utilising VoIP technology. Essentially a Wi-Fi-enabled tag with built in VoIP capability, the device can be worn around the neck and allows individuals to be tracked and contacted.

  • One application for the device would be in hospitals, where the doctor, nurse or surgeon who is nearest to an incident could be alerted by a message transmitted to that individual's tag. The request could be in the form of a short voice-alert or a text message.

  • Together with Magicomm and Nokia, IBM has created a digital pen and paper system to allow users to transmit written documents via a mobile phone or upload the information into a laptop. The pen has a unique ID in a similar fashion to an RFID tag. Data is time-stamped so updates of forms can be detected.

    The digital pen has a built-in digital camera, an image-processing unit and a Bluetooth radio receiver. By writing over the special patterned paper, which consists of millions of tiny dots, it is possible to identify the exact location of the pen and deduce the words being written. The image processor then uploads all the resulting information into the pen's memory which can store several fully written pages.
