Abstract
A transaction medium comprises a non-e-paper portion and a passive e-paper display portion to display a first expression of an authentication element in a secure representation. The first expression is related to a second expression of the authentication element, wherein a comparison of the first expression and the second expression determines authentication.
Claims15
A transaction medium card comprising:
- a non-e-paper portion;
- and
- a passive e-paper display portion imaging by receiving charges on an imaging surface of the passive e-paper display portion, the passive e-paper display portion comprising a single functional coating layer providing the imaging surface, and the passive e-paper display portion to display a first expression of an authentication element in a secure representation, wherein the first expression is related to a second expression of the authentication element, wherein a comparison of the first expression and the second expression determines authentication;
- the medium further comprising:
- a forensic security indicia formed on the passive e-paper display portion, wherein the forensic security indicia is linked to the first expression of the authentication element,
- wherein the forensic security indicia is separate from, and independent of, the second expression.
3 more elements
A transaction system comprising:
- a terminal including:
- a first authorization module to determine user authorization upon communicative coupling of a transaction medium card relative to the terminal, wherein communication with the user occurs via at least one of a display of the terminal and a passive e-paper display portion of the transaction medium card;
- an imager to write, upon user authorization, a secure expression of an authentication element in the passive e-paper display portion of the transaction medium card via non-contact application of charges to an imaging surface of the passive e-paper display portion;
- and
- a reader to read the secure expression from the passive e-paper display portion,
- wherein authentication is determined via a comparison of the secure expression to a non-secure expression visible on a non-e-paper portion of the transaction medium card,
- wherein the terminal includes a forensic security reader to detect forensic security indicia on the non-e-paper portion of the transaction medium card.
4 more elements
A non-transitory computer readable storage medium storing instructions, executable on a processor, to:
- determine, via a terminal, user authorization to engage in a transaction via a first security challenge in relation to a transaction medium presented at the terminal;
- upon user authorization, determine authentication via:
- writing, via the terminal, a first expression of an authentication element in a secure representation in a passive e-paper display portion of the transaction medium via non-contact application of charges to an imaging surface of the passive e-paper display portion;
- reading, via the terminal, the first expression;
- and
- performing a second security challenge via comparing the first expression to a second expression of the authentication element and confirming authentication upon a recognized relation between the first expression and the second expression;
- and initiate a transaction via the transaction medium upon authentication,
- wherein determining user authorization via the first security challenge comprises:
- reading, via a reader of the terminal, a variable PIN on the passive e-paper display portion of the transaction medium;
- and
- revising, via an imager of the terminal, the variable PIN on the passive e-paper display portion after completion of the transaction.
