Abstract
A contactless card includes an arrangement of a plurality of tactile sensors along the edge, an arrangement of a plurality of tactile sensors on the surface or surfaces, an arrangement of a plurality tactile of sensors along the edge and on the surface or surfaces. The arrangement of a plurality of tactile sensors captures the interaction of the user's hand and the contactless card to generate a unique binary string. In addition to the validation of the identifying information embedded within the memory of any existing contactless credit card, debit cards, prepaid electronic cash card, loyalty card and access card, the user's identification is also validated through the binary string. An irreversible mathematical equation can be used to compute the identifying information and binary string to generate the validation Radio Frequency Identification signal.
