Photograph barcode & find book
Use Take photo & scan to read the ISBN without saving the picture to your phone. Then find the book details and search eBay by title.
Ready to scan. Point the rear camera at the printed barcode (not the book cover).
Tip: For a book, scan the 13-digit EAN/ISBN barcode on the back cover. Move back slightly until the whole barcode is sharp.
Step 1 — Take a photo & scan ISBN
Photograph the ISBN barcode directly in ResellerRobot. The photo is read for its number and is not saved to your phone or uploaded to inventory. Keep the complete barcode and its white margins in view.
No photograph selected.
Enter or scan a 10- or 13-digit ISBN to look up book details automatically.
