Consider a scenario where an NGO wants to distribute cash to farmers for the sole purpose of buying seeds to plant for the new season. To achieve this, NGOs are offered a portal that they can use to make a bulk transfer of eVouchers which are received by beneficiaries in form of an SMS or directly loaded on beneficiary MamboPay cards. These can then be redeemed from participating merchants. The eVouchers are non-transferable and hence can't be exchanged for cash.
Note that, un-used Vouchers are reversed back to the sender hence un-used funds are never lost. Each voucher has an expiry date.
