New applicants have the choice of being issued with a Virtual CCDO Smart Card in addition to a physical CCDO Smart Card. The virtual card works by way of an application downloaded to the cardholders phone, saving the need to carry cards on site. All CCDO cards can now be stored on the Vircarda App. The virtual card is then scanned by the site Supervisor on entry to the site, using the same software used for reading a physical card.
