How to Scan Product Barcodes (UPC, EAN, ISBN & Code 128) on iPhone

Step-by-Step: Scan Any Product or Package Barcode on iPhone

1. Download and open QR Code Reader & Generator

   Install QR Code Reader & Generator free from the App Store and tap the Reader tab (or the scan button on Home).

2. Center the barcode in the camera viewfinder

   Hold your iPhone 4 to 8 inches away from the UPC, EAN, ISBN, Code 128, or PDF417 barcode. Tap the flashlight icon in the top-right corner if the barcode is in low light.

3. View, copy, or look up the barcode number

   As soon as the barcode is recognized, the app displays the decoded digits or alphanumeric code, saves it to your Home history, and lets you copy or share it in one tap.

Tips for Scanning Glossy or Curved Barcodes

• Avoid direct glare: On shiny plastic packaging or beverage cans, tilt your iPhone 10–15 degrees so overhead lights don't reflect white glare across the black bars.
• Use the built-in flashlight in dim rooms: Tap the flashlight icon at the top right of the scanner screen to illuminate small EAN-8 or UPC-E barcodes.
• Scanning multiple items? Turn on Batch Scan in Settings so you can scan an entire shelf without leaving the camera view.
