Voucher

The process is the same as with mint PID.

After purchase, go to your personal center, find Vouchers, and view the list of your vouchers to check the details.

Voucher redeem

When purchasing a voucher or obtaining a voucher through an offer, users can redeem the voucher into PID. After redemption, the user gains all privileges, equivalent to those who directly purchased PID. If a user has already purchased PID, they cannot redeem the voucher.
