Abstract
Abstract A secure document comprises a pliable fabric comprising human-readable information. The secure document further comprises a memory attached to the pliable fabric in which machine-readable information about the secure document is stored. The secure document further comprises an interface attached to the pliable fabric and coupled to the memory that, when a reader device reads the secure document, transmits at least a portion of the machine-readable information stored in the memory to the reader device.
