Scanning a barcode

Scanning is the fastest way to add a manga to your collection. Most physical manga volumes have a barcode on the back cover containing the 13-digit ISBN — that’s all we need.

How to scan

  1. Open the Scan tab from the bottom navigation.
  2. The camera will activate and show a scanning frame.
  3. Hold the back of your manga 4–8 inches from your camera, with the barcode inside the scanning frame.
  4. Keep the volume steady — we’ll detect the barcode automatically. No tap needed.
  5. When we find a match, a result card slides up from the bottom of the screen.

What happens after a scan

The result card shows one of four outcomes:

Tips for cleaner scans

  • Good lighting helps. Tap the flashlight icon in the corner of the scanner to turn on the torch in dim rooms.
  • Hold steady, don’t move. Let the camera focus before expecting a read.
  • Flatten the cover. Slight curling on paperback covers can throw off the read. Press the cover flat against a hard surface if needed.
  • Try a different angle. Tilting the volume 10–20° sometimes helps cameras find the barcode contrast.
  • Clean your camera lens. A smudged lens is the most common cause of slow scans.

Manual entry as a fallback

Can’t get a barcode read? Tap Enter ISBN Manually at the bottom of the Scan tab and type the 13-digit ISBN by hand. See Entering an ISBN manually.

Battery and warmth

Extended scanning sessions can cause your phone to feel warm. This is normal — the camera and barcode-detection processing are both active. We recommend taking short breaks every 50–100 scans.

Privacy

The scanner uses your camera in real-time to detect barcodes. Images are processed on-device and are never uploaded or stored.
