+   - **Expired** : The voucher has passed its validity period but still has a remaining balance.
+   - **Used Up** : The voucher was fully used during its validity period.
+
+2. For pay-as-you-go products, the deduction order after order confirmation is: vouchers first, then cash.
+3. For pay-as-you-go products, eligible vouchers will be automatically applied to offset charges at each billing cycle until the voucher expires or its balance is depleted.
