Extranet system employed by the company, enables Tesco to use the Internet to create proprietary and customised information flows between the company and its business partners. The system connects business partners online behind virtual firewalls, bringing more flexibility, scalability, extensibility and integration across the distribution channels. Extranet also helps to extend the key information on business partners throughout the supply chain and facilitate collaborative relationships with partners. Market exchanges hold the promise of extending Tesco’s reach, delivering buyers to their virtual doorstep from around the world. Other examples of the most efficient technological advances that support daily business operations of Tesco are wireless devices, intelligent scale, electronic shelf labelling, self check-out machine and radio frequency identification (RFID) systems. This technology is an effort to maintain Tesco’s ability to handle an increase in product/service volume while controlling costs; it also enables to be innovative and market oriented.
