Abstract: A method of conducting transactions between a customer device and a merchant device is presented. The method entails receiving login information from the customer device at a merchant venue, assigning a ticket to the customer device, receiving, from a merchant device, a predetermined amount of currency associated with the customer device, associating the predetermined amount of currency with the ticket, receiving, from the customer device, an approval to carry out a financial transaction for at least the predetermined amount of currency using a payment card number, and receiving, from a gateway, a notification that the financial transaction is completed using the payment card number.

Abstract: A method of conducting a transaction between a merchant Point of Sale system (POS) and a customer device is presented. The method entails obtaining a ticket directly from the merchant POS via a plug-in application, the ticket including a merchant identification, a customer identification, ordered items, and prices of the ordered items; activating a web portal to interface the customer device; reporting ordered items and prices to the client device, and receiving payment authorization from the customer device; generating a login token via a payment engine to contact a gateway to a financial transaction site; and in response to receiving authorization from the gateway, contacting the merchant POS to complete the transaction.

Abstract: According to examples, an apparatus may include a security enclosure, a main processor housed in the security enclosure, and a physical security monitoring control unit (PSMCU) processor housed in the security enclosure. The PSMCU processor may cause the apparatus to switchably operate between a first mode and a second mode. In the first mode, the PSMCU processor may allow access by the main processor to a first cryptographic key while preventing access by the main processor to a second cryptographic key. In addition, in the second mode, the PSMCU processor may allow access by the main processor to the second cryptographic key while preventing access by the main processor to the first cryptographic key.

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.
