近年，由於非同質化代幣(NFT,non-fungibletokens)可以達到將數位資產的權 益證明記錄永久留存於區塊鏈，成為一種保護數位資產免於非法複製與傳播的管 道。NFT 興起帶動各種 NFT 衍生商品，多國官方郵政機構陸續發行 NFT 郵票， 此舉也滿足集郵愛好者，能同時擁有實體郵票與虛擬郵票數位版收藏品。有鑑於 NFT 與郵票商機的潛力，以及觀察到目前 NFT 的衍生商品多數僅運用傳統黑白 模塊二維碼為串聯虛實的媒介，美觀度與吸引受眾的影響有限。因此，本研究以 實驗研究法，將 NFT 數位圖檔作品為基底，透過 Matlab 程式運用資訊隱藏技術 演算法，將黑白模塊 QR Code 融合至彩色圖像，生成人眼可辨識的視覺化 QR Code 圖面，且實體郵票與 NFT 進行虛實整合，分別輸出兩種不同型態底圖的 NFT 郵票。第一種為靜態版底圖 NFT 郵票，第二種為搭配 100 LPI 柱狀透鏡(光 柵板)，所使用的動態成像 NFT 郵票，以此觀察跳脫傳統郵票形式時，動態 NFT 郵票是否能因其獨特的使用體驗，進而提升使用者對其 NFT 的使用者參與度成 效以及兩種郵票之間的加值程度差異。
本研究所收集的使用者數據顯示動態 NFT 郵票的使用者無論是參與度成效 或是刺激實體 NFT 郵票的增值效果、購買數量皆優於靜態 NFT 郵票。靜態與動 態 NFT 郵票樣品數量皆為 30 份，比較後兩者使用者參與成效中的 QR Code 掃 描次數動態郵票比靜態郵票高出 6 倍，而動態郵票比靜態透過 OpenSea 平台執 行 NFT 轉移次數高 7.5 倍，實際交易次數也多出 1 次，由此可見，動態展示相較 於靜態展示的平面設計商品，更能取得銷售優勢。同時，本研究所使用的視覺化 QR Code 技術，以 600 dpi 解析度時，能將長寬約 2 公分的 QR Code 根據輸出設 備將印刷條件之植入與讀取最佳化，非常適合應用在面積有限的有價票券、郵票、 具紀念意義的印刷品文件上。透過中華郵政輸出後，產出獨特且能將實體郵票進 行與虛擬 NFT 數位收藏品串聯之媒介，為目前全球首款具備郵票寄送功能並結 合圖像視覺化二維碼應用的 NFT 郵票，此研究結果也可以供未來郵政單位，可做為郵票多元化與加值應用的實際參考案例。

In recent years, non-fungible tokens (NFT, non-fungible tokens) can permanently store the proof-of-stake records of digital assets in the blockchain, becoming a channel to protect digital assets from illegal copying and dissemination. The rise of NFT has driven a variety of NFT derivatives, and official postal agencies in many countries have successively issued NFT stamps. This move also satisfies stamp collectors, who can have both physical stamps and virtual stamp digital collections. In view of the potential of NFT and stamp business opportunities, as well as the observation of current NFT derivatives, most of them only use traditional black-and-white module QR codes as a medium for connecting virtual and real. the impact is limited.
Therefore, this research is based on the experimental research method, based on the NFT digital image file, and uses the information hiding technology algorithm through the Matlab program to fuse the black and white module QR Code into a color image to generate a visual QR Code image that can be recognized by the human eye. and printed on the Chunghwa Post Personalized Stamp Service Platform. Produced the first physical stamp that uses a visual QR code surface for NFT virtual and real integration. At the same time, this research will produce two different types of base maps for printing and output, the first is a static base map NFT stamp, and the second is a dynamic imaging NFT stamp used with a 100 LPI lenticular lens (grating plate). . In this way, we can observe whether the dynamic NFT stamps can improve the user's participation in their NFTs and the difference in the value-added degree between the two stamps due to their unique user experience and value-added applications when they escape from the traditional stamp form.
The results of this study show that users of dynamic NFT stamps are better than static NFT stamps in terms of participation effectiveness, stimulating the value-added effect of physical NFT stamps, and the number of purchases. Through this experiment, it was observed that the difference in user participation effect and the value-added effect of NFT stamps are both the best effect of dynamic NFT stamps. The number of static and dynamic NFT stamp samples is 30. Comparing the user participation results of the latter two, the number of QR Code scans in the dynamic stamp is 6 times higher than that of the static stamp, and the number of NFT transfers performed by the dynamic stamp through the OpenSea platform is 7.5 times higher than that of the static stamp. times, the actual number of transactions is also doubled. At the same time, the visual QR Code technology used in this research, at 600 dpi resolution, can optimize the implantation and reading of the QR Code with a length and width about 2 cm according to the output device and the printing conditions. Through Chunghwa Post After output, a unique medium that can connect physical stamps with virtual NFT digital collectibles is produced. It is currently the world's first NFT stamp with stamp delivery function combined with image visualization QR code application.
