Questions
How do I take a left thumb impression for an online form?
Press your left thumb on a blue or black ink pad, then press it once on plain white paper. Scan it or photograph it flat in daylight, crop close around the print, and upload the photo here.
Which size should I choose?
Use the size written in your form's official instructions. If it says 20–50 KB, pick that option; if it says 10–20 KB, pick the other. Also check the pixel size your form asks for.
Will the thumb print be cropped?
No. The whole print is kept and fitted inside a square white canvas, so no ridge lines are cut off.
Is my thumb impression uploaded anywhere?
No. Resizing happens on your own phone or computer. The image never leaves your device.
