Systems and methods for cards and devices operable to communicate via light pulsing

Abstract

A card is provided with a light sensor operable to receive information via light emitted from a display screen or another source of light. Accordingly, a mobile telephonic device or portable computer (e.g., tablet computer) may communicate information to a card via light pulses. Information communicated via light may include, for example, points balances, credit balances, debit balances, transaction history, software updates, coupons, promotions, advertisements or any other type of information.
