The multi-function card is adapted to aggregate some or all of the user's earned reward points from the reward accounts and credit the aggregated points into a single reward exchange account on the multi-function card. The user may then select an item for purchase with the accumulated reward points from the multi-function card. The item is provided to the user in exchange for a subset or all of the reward points from the multi-function card."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Portable hand-held multi-function device with multiple transaction and reward accounts","description":"A system and method for operating a reward points accumulation and redemption program wherein a user earns reward points from a plurality of independent reward points issuing entities, with each track","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8478638","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
