Getting a Clean Result First Try
Signature rejections usually trace to the wrong KB range, the wrong aspect ratio, or a non-JPG format. Because this page pre-locks all three to the verified RBI Assistant numbers, uploading a clear scan on plain white paper in black ink is usually enough to clear the portal's validation on the first attempt.
