Access Medium

An access workflow system comprising:

• a terminal including:
• a first module to authorize use of an access card upon receipt of a one-time code;
• an imager to write, upon authorization via the first module, a secure representation of a first access element on a passive e-paper display portion of the access card;
• and
• a first reader to optically read the first access element;
• and
• a second reader to read a second access element from a memory resource of the access card,
• wherein authentication is determined via evaluation of the first access element and evaluation of the second access element.

A computer readable medium storing instructions, executable on a processor, to:

• authorize an access medium at a terminal per a one-time code;
• upon authorization, determine authenticated access via:
• writing, via the terminal, a first secure access element on a passive e-paper display portion of the access medium;
• reading, via the terminal, the first access element;
• reading a second access element from a memory resource of the access medium;
• and
• evaluating the first access element and evaluating the second access element;
• and
• initiate access via the access medium upon successful authentication.
