Heat-Sensitive Business Cards That Look Like Ever-Changing Polaroid Snaps

Austrian design studio Bureau Rabensteiner has produced a brilliant, heat-senstive business card for Vienna-based photo producer Natalie Daniels.

Printed with thermo-sensitive ink, the business card allows those who receive it to literally leave their marks on it—and turn it into a constantly changing Polaroid picture.

When heat is applied to the black varnished surface of the card, it loses color and patterns are temporarily created on it.

This interactive business card will leave an impression by allowing people to have fun with it, using their fingers, lips and basically anything warm.
