Voucher code redemption via SMS

摘要

A voucher verification system is based on SMS message-based processing of voucher verifications by a central verification authority. Merchants may establish an account with the system and then register mobile communication devices and those of employees by sending an SMS-based registration request to the system. Once registered, the merchant and employees may verify the status of vouchers by sending SMS-base verification requests to the system. Verifications of voucher status are returned to the merchant mobile device via SMS messaging.
