什麼是QR碼產生器?

QR碼(Quick Response,快速回應碼)是一種二維條碼,手機可以即時掃描。它被廣泛用於選單連結、分享聯絡人、WiFi憑證、付款URL和活動報到。QR碼很穩健:它們內建了錯誤更正功能,因此即使部分損壞或被遮擋也仍然可讀。對於印刷材料,請以高解析度產生,並在大規模印刷前進行測試。

常見使用場景

  • Print a QR code on a restaurant table tent that opens the digital menu when scanned.

  • Add a code to a conference badge or flyer that links to an event schedule or registration page.

  • Put a QR code on product packaging pointing to setup instructions or a warranty page.

  • Drop a scannable link into a slide deck so the audience can open a demo on their phones.

  • Generate a code for a payment or donation URL to display at a market stall or checkout.

  • Create a quick code linking to your portfolio or LinkedIn for in-person networking.

常見問題

一個QR碼最多能容納多少資料?
最多4296個字母數字字元或7089個數字。對於URL和短文字來說,容量綽綽有餘。
QR碼會過期嗎?
靜態QR碼(如這裡產生的)永不過期。來自付款服務的動態QR碼可以編輯,但需要帳戶。
