Vip customers should apply for VIP cards at the counter (not cash counter or VIP service window in principle) of the signing network with the VIP customer signing certificate. VIP customers can choose their own numbers in the directory of existing unreleased VIP cards in outlets. After screening by the Personal Quality Customer Relationship Management System (PCRM System), the customers whose daily average financial assets in the previous 12 months reached more than 5 million yuan (inclusive) were called diamond card customers.
