Badge reader- Badge readers can be implemented to help prevent unauthorized access. In this type of environment, employees are given badges such as proximity cards or smart cards. When the employee scans the badge, he or she is allowed entry to the area.
Smart card- Smart cards are cards that are typically the size of your driver's license or credit card. The embedded memory and chipset in these cards can store identification and authentication information. A smart card can also be programmed to use as a cash card that is seen in many organizations where employees may use their employee badge to purchase lunch in an onsite cafeteria.
