The Bend Test: Flex and Snap of a Genuine Card

A gentle flex tells you a lot: genuine cards have a springy, consistent feel and snap back flat, while many fakes feel stiff, flimsy, or stay bent.

Caution: Bend only slightly. Over-flexing creases the card and lowers its value — never do this to a card you do not own.

What this checks

The stiffness and memory of the card stock. The genuine paper-core-paper construction has a distinctive springiness.

Compare your card against a verified genuine scan like this — look for a smooth, even bend that springs back flat with a soft, consistent feel. A counterfeit instead shows: too stiff or too floppy, an uneven bend, a plasticky feel, or the card holds a crease and does not return flat.
