The ground truth. Your bank's own placard, unmodified, against each app — the baseline every edited copy is compared to.
Expected
The QR is located within a larger screenshot — surrounding app chrome, a status bar, cropped edges — and decoded.
Limitations
- Decode-only. No app opens and no money can move, so this method is safe to run as often as you like.
- A heavily compressed or small screenshot may not decode. That is a limit of the image, not of the payload.
Prerequisites
- Something to decode.
