Capture & review

Serial number scanner: capture labels with your phone

Learn when photo OCR is the right serial number scanner, how it differs from a barcode reader, and how to capture identifiers for an inventory export.

Example serial number SN 0018-B7O2, with a reminder to compare similar-looking characters: zero and O, one and I, eight and B.

Read the number printed on the item

If your job is to get serial numbers from labels into a spreadsheet, a photo-based scanner can save the copying step. Photograph the text, extract the identifier and check it against the image before export. Keep the product or model number alongside it so the row still makes sense later.

This is different from looking up warranty details or specifications from a serial number. TagQuill extracts visible label text; it does not query a manufacturer's registration database.

Same model, different unit

Consider these two fictional monitor labels. The model is the same, but the serial identifies a different unit. Keep both fields: the model helps describe the product; the serial helps distinguish the physical item.

Manufacturer identifier conventions vary. For matching across different brands, keep manufacturer and serial number together. A repeated serial is a reason to inspect both records, not automatically delete one.

Capture a label that you can verify

Include the S/N, Serial or Serial No. heading in the frame, plus the nearby model and manufacturer. A tightly cropped string of digits loses the context that tells you what the number means.

  1. Open your inventory on the computer and choose Scan with phone. Use your phone to scan the workspace QR code and allow camera access.
  2. Hold the camera steady and square to the label. Check that glare does not cover any part of the identifier, then take the photo.
  3. Review the received record next to its source image. Compare every character, especially O and 0, I and 1, and the final digits.
  4. If a character is obscured, retake the photo. Export the reviewed serial alongside manufacturer, item and model in CSV or Excel.

Keep the identifier intact after capture

Store serial numbers as text, including leading zeros, spaces and hyphens. A spreadsheet that changes 00018427 to 18427 has changed your identifier even if the photo extraction was correct.

Check a few exported rows before a large capture session. If the destination needs different headings, save a custom export layout and reuse it. This produces an importable file; it does not establish an ongoing connection to another inventory system.
