As the number of mobile Internet users grows rapidly, more and more service providers are distributing electronic vouchers to consumers via mobile phones, which eliminates the need to carry various plastic or paper-based vouchers. Currently, electronic vouchers are available mainly in the form of text message or QR code. However, these types of vouchers are usually stored in the mobile phone that lacks secure storage and trusted execution environment. In addition, it is not efficient enough to input voucher code manually or get voucher QR code scanned when the consumer redeems the voucher. Near Field Communication (NFC) is a short-range wireless communication technology that simplifies the way of interaction between the electronic devices and guarantees a fast and secure information exchange. In this paper, we propose an NFC-based electronic voucher solution, which provides capabilities of distributing, managing and redeeming vouchers in a secure manner. The security of the voucher is ensured by storing it in the Secure Element (SE). With the proposed system, the consumer is enabled to redeem the voucher just by touching the NFC reader at the point of sale with his/her NFC phone, which offers better user experience than traditional electronic voucher solutions.
