Visible PIN

Visible PIN — your PIN code in plain sight… but not for everyone.

Forget scribbled notes and hidden memos! Visible PIN is a smart and secure app for storing your bank card PINs by turning secrecy into visibility.

At its core is a simple yet brilliant idea: you see a grid of digits, and any digit can be highlighted in color. You decide which cells are “active”—that’s where your PIN is hidden. To you, it’s an obvious sequence. To anyone else glancing at your phone, it’s just a colorful table with no meaning.

How it works:
— Create a new “card” and give it a name (e.g., “My Favorite Bank Card”).
— Choose your PIN and highlight the corresponding digits in the grid using your chosen color.
— The app never stores your actual PIN—only your unique coloring pattern.
— At any time, you can recall your code just by looking at the highlighted cells.

Security through obscurity
Even if someone sees your screen, they won’t know:
— In what order to read the digits,
— Which colors are meaningful and which are just decoration.
This isn’t encryption—it’s visual camouflage based entirely on your personal logic.

Flexibility and control
— Change highlight colors to match your mood or differentiate between cards.
— Add decoy highlights to further confuse onlookers.

Visible PIN doesn’t store your secrets. It makes them invisible in plain sight.

Because the best password is the one nobody’s looking for.
