碩士 === 大同大學 === 資訊工程學系(所) === 102 === In recent years, QR Code and NFC are applied more widely. The smart phones have been more popularized. Unfortunately, not all smart phones are built with NFC ability. The requirements of QR code applications are a camera-enabled smart phone or handheld devices.Most services provider support QR Code and NFC techniques concurrently. These two techniques support fast linking and complete connection and allow users and vendors obtain considerable convenience.
Original QR Code need only one camera and screen on two ends of communication, separately. If the QR Code is copied, the message will be leaked easily. In contrast, NFC using repeatedly exchanges to ensure the safety of message.The first message in the mechanism of NFC is an activation code that provents messages leakage.The exchange mechanism of QR Code proposed in this thesis is similar to NFC. The first QR Code is an activation code, and following QR Codes are the encrypted messages. The receive device need decrypt them to decode, authenticate or reply these messages.
In this thesis there are three applications are modified to use the QR Code exchange mechanism. First, using QR Code for electronic trading. Second, using QR Code to unlock electronic door locks. And the last one, using QR Code to network connection.
