上班族到公司報到的第一天，首件要事就是辦理一張員工識別證；去參觀商業的特展，在入場處通常要用名片登記，換取一張參觀證。這些代表自己身份的識別就是你的『識別證』，也就是所謂的 “Badge”。

原先的『識別證』設計都會在卡片上印上你的大頭照、姓名、職稱或是ID號碼；目的當然是方便讓人核對你的身份。後來為了結合了門禁管理、員工餐費的功能，把電子憑證加進了識別證；從此在公司生活的每一天就少不了它，並用吊帶掛在脖子上隨身攜帶。

NFC-TO-GO 把這樣的使用情境落實到日常的生活中，推出所謂的『NFC Badge』應用，將智慧手機正夯的 NFC感應與數位憑證技術結合，打造所謂的『NFC自憑證』，可以簡單又安全地使用在以『我』為中心的時尚生活之中。

基本功：NFC 電子名片

把 NFC Badge卡 做成『NFC Badge名片卡』，來作為自己的識別證，就是最基本的應用。但是有別於商務上的員工識別證，Badge的資料是記載擁有者所要公開的訊息，放在雲端專屬的個人的資訊主頁(可當作名片)，可以透過 NFC手機，以感應卡片的方式來分享名片的內容。

\"article

『電子名片』應該是自媒體發達的現在，最潮的應用之一。NFC Badge 名片卡，可以透過 NFC Badge App ( iOS | Android ) 的安全認證機制，經由輸入個人設定的卡片存取密碼(8位數字)，並感應Badge卡來登錄雲端，即可直接編修自己的『資訊主頁』；未來想要再更新時，只要重複上述的感應登入步驟，就可以隨時隨地快速更新自己資訊主頁的內容。

要與他人分享自己的電子名片時，只要拿出Badge卡讓對方的手機感應一下，就會顯示在他的手機上；可以選擇直接加入自己的社群好友或粉絲、發訊息，或是一鍵下載聯絡訊息到手機 聯絡人 的通訊錄之內。

進階功：簽發自己的NFC 憑證

再來是所謂的『NFC Badge金鑰卡』，是一張兼具電子名片與個人簽證功能的卡片；當然不同於名片卡的是多了一把隨機生成的加密『私鑰(Private Key)』，使用相當於區塊鏈相同等級的加密演算法，可以透過『NFC Badge』APP來製作電子簽章(Signature)，並寫入到同樣以 NFC 標籤 (Tag) 製成的憑證貼標 (Seal Sticker) 內；然後你可以去編輯此憑證的資訊主頁，並將 Seal標籤 貼到自己的作品上。

\"article

當他人用手機感應到 Seal標籤時，一樣會在其手機顯示此Seal的資訊主頁，就是你的作品內容或是介紹；當然，最特別的設計有2點：

  1. 在Seal的資訊欄的尾端，會顯示一超連結區塊，是原先在Badge設定的『Seal連結字眼』(例如：原創者)，以便直接連結來顯示原Badge的資訊主頁。
  2. 接在Seal資訊之後，會出現一個『驗證』的按鈕，按下後，可以啟動『NFC Badge』APP 來再次感應Seal標籤，除了確認此標籤的UID是否合法(未被仿造)外，還會讀取其內的簽章，然後以存放在雲端的『公鑰(Public Key)』來驗證其真偽性。

特異功：作為線下的冷錢包 (HD Wallet)

『NFC Badge錢包卡』是NFC Badge系列為區塊鏈應用所特別設計的一款NFC卡片；也是在NFT的盛行之際，打開虛實整合的一個『任意門』。因為錢包管理的安全與線下保存，一直是非常重要而且是攸關自身資產的熱門話題。

鏈友熟悉的『小狐狸』MetaMask，是 “用於與以太坊區塊鏈進行互動的軟體加密貨幣錢包。它可以通過瀏覽器擴充程式或行動應用程式讓使用者訪問其以太坊錢包，與去中心化應用進行互動。”～Wiki。而在新版的小狐狸，開始提供『連接HD Wallet』的選項，可以使用冷錢包(指不連網路的錢包，所以相對安全很多)來簽署交易資料。

NFC Badge錢包卡，則是一張兼具電子名片與個人冷錢包的卡片；採用相容於 BIP-44 架構規範的 HD Wallet (Hierarchical Deterministic wallet)，可以從單一個 seed 產生一樹狀結構儲存多組 Keypairs (私鑰和公鑰)。其優點是可以方便的備份(採12組助憶詞)、轉移到其他相容裝置，以及分層的權限控制等。而最大便利之處，便是可以搭配MetaMask來使用。NFC感應支付，幾乎已經成為現今智慧型手機的標配。
