電腦如何直接掃描二維碼？

隨著行動裝置的普及，二維碼的使用越來越廣泛。但當我們需要在電腦上掃描二維碼時，往往需要使用額外的軟體或裝置。 php小編柚子為大家整理了一份詳細指南，介紹如何在電腦上直接掃描二維碼，無需任何額外工具。以下內容將詳細介紹三種便利方法，幫助您有效率地掃描二維碼，解決您的難題。

一、電腦如何直接掃描二維碼？

現在有一個很奇怪的問題，幾乎所有的二維碼識別功能都是在手機上，而電腦上的都沒有。

但是如果需要在電腦上辨識二維碼咋辦？去搜尋了一下，發現沒有，或很少。

如果自己的工作就是要辨識很多二維碼並且對它做分類，要怎麼實現呢？

這裡分享一個小軟體，可以實現在成千上萬張圖片中找到有二維碼的圖片，並且將其挑出來並分類好。

軟體叫做《萬圖找碼》，下面介紹它的使用。

這個軟體可以自行去網路搜尋下載到的，這裡就不說了，本次對下面這個資料夾的一堆二維碼圖片做分類軟體壓縮包解壓縮後，雙擊開啟主程式軟體開啟後，介面如下：第一格子選擇保存分類前的資料夾，第二個格子選擇要保存分類後的資料夾最後點擊，只要一下子，就全部分類好了去保存的資料夾看看，可以看到，凡是包含了二維碼的文件，都已經識別出來，並且做了分類

7，到這裡就搞定了，如果你有上萬張圖片要分類，要人來弄的是會瘋的，用這個軟體只需要一會兒就行。

二、電腦怎麼掃描二維碼？快速了解電腦二維碼掃描方法

什麼是二維碼？

二維碼（QR碼）是一種能夠攜帶訊息的矩陣條碼，它可以儲存比普通條碼更多的資訊。通常用於快速識別連結、文字或其他資料。二維碼的使用已經非常普遍，它可以透過手機掃描來獲取訊息，那麼在電腦上怎麼掃描二維碼呢？

使用電腦自帶相機掃描二維碼

使用第三方掃描工具

除了使用電腦自帶相機掃描二維碼外，也可以透過第三方掃描工具來實現掃描。有一些軟體可以將手機上掃描到的二維碼快速傳輸到電腦上，透過這些工具，實現了電腦對二維碼的掃描功能。你只需要在手機上完成掃描，然後在電腦上即可取得對應資訊。

使用掃描器

如果你需要頻繁地在電腦上掃描大量二維碼，那麼使用掃描器可能是個不錯的選擇。現在市面上有一些高速文件掃描器能夠快速、準確地掃描二維碼並將資訊傳輸到電腦上。當然，這需要購買額外的設備，不過效率會更高。

結語

總的來說，在電腦上掃描二維碼有多種方法可供選擇，你可以根據自己的需求和具體情況來決定使用哪種方式。如果只是偶爾需要掃描一兩個二維碼，使用電腦自備攝影機或第三方掃描工具就可以滿足需求。如果在工作中需要大量掃描二維碼，考慮購買掃描器可能更有效率。
