Membership card function: Enjoy product discounts (such as discount rates set by membership card category).

Restrictions: ① Special promotion products do not enjoy member discounts (based on the promotional price). ② You must first swipe your membership card before entering the product, otherwise you cannot enjoy the discount.

Membership card operation steps: Press the F7 key directly on the POS interface to open the membership card information input window. Manually enter the membership card number. If the member exists, the interface will display the member information (such as name, discount rate, points, etc.). By scanning the code or manually entering the product code, the system automatically calculates the price based on the member discount.
