1.打開你手機的QR code reader
2.將你的裝置對準於QR code上方,好加以掃描:此時可能會有兩種情形
*裝置自動掃描成功code
*部分用戶需要使用內建按鍵,加以對圖形照相(snap a pic.),好加以掃描
3.成功掃描,若無法讀取;必要時請等待幾秒,或點擊裝置螢幕好加以掃描
* 有何不同(standard UPC Barcodes and QR Codes)?
- "UPC Barcodes are linear black and white groupings found on most product packaging that have mainly been used by retailers to identify products. QR codes are an array of small black squares arranged in a pattern that store more complex information."
- 前者主要用於辨認產(商)品，後者主要是儲存較複雜之大量資訊內容。
* 使用QR code之注意事項:
1.先行確保自己掃描的是有效條碼
2.掃描時QR code圖形盡量是保持置中,並保有適宜周邊空間
3.請避免掃描時出現陰影
*此款是一個隨拍即可翻譯的學習App，準確度高。

- 1994年由日本Denso-Wave公司發明
- QR code比普通條碼可儲存更多資料 (無需像普通條碼在掃描時需準確對準掃描器)
- QR code呈現正方形，僅有黑白兩色;在圖形中的三個角落，印有較小像「回」字的的圖形。這三個圖形是幫助(解碼)軟體定位時用的，使用戶不需特別刻意對準，掃描時資料仍可被讀取。
- 也可稱作「行動條碼」，是一種矩陣式黑白相間的點狀或條狀圖形。
*優缺點:
1.能表示文字、圖片(形)、聲音等資訊
2.容量大、可靠性高、資料保密佳、修改資料方便
3.此款矩陣式圖形可儲存達數百個數位或中文字

1.對行動條碼使用的陌生，以至於對資訊缺乏探索興趣
2.臨時忘記帶手機或是平板等設備
