If a customer scans a promoter's poster again within the validity period of the promoter binding, will the binding time change?

中文 1. If a customer rescans the promoter's poster within the validity period, the validity period will be recalculated. 2. Within the validity period, each time a customer visits the promotion link or scans the QR code, the first binding time will be automatically updated; 

 For permanent binding (non-customer snatching mode with a permanent validity period), the binding time will not be updated again.
