MasterCard believes #AcceptanceMatters. This year at Pride Fest, Mastercard demonstrated their support of global acceptance by installing a restroom that accepts all humans, no matter your gender identity.
How did you gain access? Simply by proving that you’re human by placing your hand on the pulse sensor on the door; the technology read your heartbeat and wirelessly unlocked the door to our restroom.
We developed a custom API for a Bluetooth-controlled lock, combined with a pulse sensor and an Arduino Yun micro controller that wirelessly communicated with the restroom lock.
When visitors placed their hand on the sensor, LED lights lit up the heart to the rhythm of their heartbeat and wirelessly unlocked the door to the restroom -- promoting acceptance for all humans.
