Abstract
Systems and methods for providing secure smart card transactions are disclosed. Smart cards are arranged in a smart card hierarchy, the hierarchy including a first smart card at a first hierarchical level and a second smart card at a second hierarchical level higher than the first hierarchical level. A smart card reader is equipped to read smart cards and to accept personal identification (PIN) number inputs. According to one embodiment, a first PIN number is stored on the first smart card, the first PIN number corresponding to the first hierarchical level. A first security key is also stored on the first smart card. A second PIN number is stored on the second smart card, the second PIN number corresponding to the second hierarchical level. A second security key is stored on the second smart card. The PIN numbers and security keys are used to selectively lock and/or unlock a smart card.
