The PIN-Shield Register at the EFTPOS Terminal
A research poster from the School of Emergent Priorities places 4,720 PIN entries at 38 supermarket, strip-mall and food-truck EFTPOS terminals into four named cells of the PIN-Shield Register, and withholds the next trading day from any campus-retail terminal whose Exposed share exceeds a pre-registered 12% band, scoring a missing cup as Exposed regardless of the hand.
