<p>A system and method for data acquisition and processing is described which can form the basis of new and improved business and consumer services. Encoded datagram images are captured using a mobile phone or PDA or fixed line device and processed relative to a stored encoded profile such that the result of the processing can be used to access services remotely by way of a fixed or network connection and or be used to generate encoded local broadcast signals such as those sent by Bluetooth or Infra Red or WLAN or WIMAX or wireless USB and the like. In this way the capturing device becomes an intelligent service access gatekeeper such that data can be differentially extracted from visible images and used to generate encoded signals according to differential service access privileges which can be used for authenticating and granting building access, operating car park barriers, providing additional security for ATM cash point transactions, operating machinery in diverse applications and the like.</p> |
