Abstract
A card for use in secure transactions includes a card body having a first major surface and a second major surface; one or more groupings of a plurality of individual distinct symbols viewable from the first major surface, each individual distinct symbol comprising a single segment defining the individual distinct symbol that upon activation illuminates the respective individual distinct symbol; and a controller coupled to the plurality of individual distinct symbols. The controller is operable to produce a one-time password value and to selectively activate individual ones of individual distinct symbols to identify a sub-combination of the plurality of individual distinct symbols, thereby displaying an illuminated one-time password token for use in a secure transaction.
