「二維碼」和「掃碼關注」可能現在大家天天都會聽到，尤其是走在大街上會有推廣某種產品的人說「掃碼關注，免費送耳機」等。如果想真正學好英語，凡是我們經常聽到的，說到的，看到的，想到的，都值得思考如何用準確的英語表達出來。今天我們就來看一下「二維碼」和「掃碼關注」對應的英語。
二維碼是二維條碼(也叫二維條形碼)的簡稱，英文是two-dimensional barcode。微信上用的二維碼叫QR code，屬二維條碼的一種，它是Quick Response Code的縮寫，意思為「快速響應碼」。
dimensional這個詞相信大家不會陌生，我們經常說的3-D(電影)，就是three-dimensional的縮寫。
此外，barcode也可寫作bar code，意思為「條碼」，也叫「條形碼」，和二維碼不同，它是一維的。bar是「(長)條」的意思，如「長鐵條」是a long iron bar，「一條巧克力」是a bar of chocolate。
「掃碼關注」是scan a QR code to follow。例如，「請掃以下二維碼關注我們以獲取更多資訊」就是For further information, please scan the QR code below to follow us。
總結一下：
QR code (微信的)二維碼
scan a QR code to follow 掃碼關注
以下內容供大家參考：
QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to efficiently store data; extensions may also be used.
