To date, over 530,000 entry permits have been issued by the registration center for the first China International Import Expo (CIIE) which is to be held this November in Shanghai.

The entry passes consist of six major types, including exhibitor cards, trading group cards, media cards, VIP cards, security cards and staff cards, said Lu Wei, deputy head of the registration center, adding that a guide map has also been added to the back pocket of each entry permit.

It's estimated that a total of more than 600,000 passes will be issued, and the permits for exhibitors and trading groups will also help calculate the trade data during the event, Lu explained.

The expo will adopt both the pass and human face recognition to ensure efficiency and security.
