A Ninjapay Voucher is a single-time or multi-time usable coupon that can be redeemed by both Ninjapay and non-Ninjapay users to transfer funds from your Developer Admin Wallet into their wallet.

Use-cases:

* You want to gift a user but don’t know their Ninjapay username or Lightning Address
* You want to send a Voucher to a user’s email to re-engage them
* Give incentives to your team members for starting early
* You want to run a promotion where you generate 100 Vouchers and give them away to people
