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.

For an overview of what the scanner does in the store, see how the Manga Vault barcode scanner works.

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:

• Found — The volume is in our catalog. Confirm details and tap to add it. See What “Found” means.
• Coming Soon — The volume has been approved but isn’t quite live in the catalog yet. See What “Coming Soon” means.
• Pending — Someone (maybe you) has already requested this volume and it’s awaiting review. See What “Pending” means.
• Not Found — We don’t have this volume yet. You can request that we add it.

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. Camera images are processed entirely on your device — we never see or store the picture.

The 13-digit ISBN we extract from the barcode is sent to our catalog endpoint to fetch the matching volume. We don’t tie that lookup to a personal profile of what you scan.
