Abstract
According to an example, secure key component and PIN entry may include receiving a communication from a smart card control device upon connection of the smart card control device with a secure key component and PIN entry apparatus. The communication may be related to storage of a key component on a smart card that is communicatively connectable to the apparatus. The key component may be related to a Master File Key (MFK) that is formed by using a plurality of key components including the key component. In response to the communication, the smart card may be prompted to generate the key component, or entry of the key component may be received based on actuation of a keypad of the apparatus. Further, the generated or received key component may be stored on the smart card upon connection of the smart card with the apparatus.
