A QR code is a square picture with black and white patterns. When you scan it with your phone, it opens information, such as a website or a menu. Many people use QR codes every day without thinking about it.
二維碼是一張方形圖片，上面有黑白圖案。你用手機一掃，它就會開啟資訊，比如網站或選單。很多人每天都在用二維碼，卻沒怎麼注意到。
You can find QR codes in cafes, stores, and on posters. Some restaurants use them for digital menus. Some shops use them for quick payment. They can save time and reduce paper.
你在咖啡店、商店和海報上都能看到二維碼。有些餐廳用它做電子選單，有些店用它來快速支付。它們能節省時間，也能減少紙張。
To scan a QR code, open your camera app and point it at the code. A link usually appears on the screen. Tap the link to open it. If your phone does not support this, you can use a QR scanner app.
要掃二維碼，開啟相機，對準二維碼。螢幕上通常會出現一個連結。點一下連結就能開啟。如果你的手機不支援，可以下載一個二維碼掃描應用。
QR codes are convenient, but you should stay careful. A code can also open a fake website. Before you tap, check the link name. If it looks strange, do not open it.
二維碼很方便，但也要小心。二維碼也可能帶你去假網站。你點之前先看一下連結名稱，如果看起來很奇怪，就別開啟。
If you use QR codes often, a simple rule helps: trust the place, not the code. Use codes from official signs or trusted stores. This way, you can enjoy the speed and stay safer at the same time.
如果你經常用二維碼，一個簡單規則很有用：相信場所，不要盲信二維碼。儘量用官方標識或靠譜商家的二維碼。這樣你既能享受方便，也能更安全。
