A bar code reader system is required to be integrated into an energy dispenser that is able to read a variety of bar code formats printed on a variety of media. The bar code reader system accepts both bar encoded cards having very low aspect ratios and other printed bar encoded media having differing aspect ratios. The system also provides a robust scanning pattern such that other printed bar encoded media can be placed into a receiving cavity without regard to a particular orientation. Further, the system provides a sensing mechanism capable of determining when a card has been inserted into the system or when another bar encoded media has been placed into the receiving cavity.
