# Use a voucher

> Check where a member can present their voucher and when it expires.

A member's voucher shows the benefit, **Use at** location, code, and any expiry or terms. Ask them to follow those details when they use it.

## Retailer vouchers

The member presents the QR or code at the participating retailer. The retailer's terms determine when and how it can be used. An **Issued** status in Hydra doesn't by itself tell you whether the retailer has accepted it yet.

## Your own vouchers

Agree with your team how you'll honour and record your own offers. Hydra can send the member a display voucher, but the **Redeem** screen can't currently mark that house voucher used. That also means Hydra can't prevent a code from being presented twice through this screen.

A saved voucher may have a fixed **Valid until** date. A campaign's **Reward expires** setting counts from the day the reward is earned. For a retailer voucher, use the date and terms on the actual issued voucher; a shorter campaign setting might not change the retailer's till code.

If a member asks about their vouchers on WhatsApp, they should keep the actual voucher message. The `WALLET` reply gives balance information but doesn't open a list of usable rewards.
