Obviousness

I cannot perform a comprehensive obviousness analysis of US patent 11328286 under 35 U.S.C. § 103 because the provided patent text does not include a list of specific prior art references (e.g., other patents, publications) that would be cited by an examiner or used in an obviousness challenge.

The "Prior art keywords" section lists general terms such as "card," "payment," "operable," "user," and "transaction." While the "BACKGROUND OF THE INVENTION" section describes existing credit card technologies (conventional magnetic strip cards, smart integrated circuit chip cards, and RFID cards), it does not provide specific details, publication numbers, or dates for these technologies to be used as identifiable prior art references in a § 103 analysis.

Without specific prior art documents to combine, it is impossible to identify combinations, describe their disclosures, or explain the motivation for a person having ordinary skill in the art to combine them to render the claims of US11328286 obvious.
