Abstract: A technique for providing a pay-by-name payment experience is disclosed. A point-of-sale (POS) system at a store receives information identifying an account with a central server from a payment card using a short-range wireless technology. In response to that, it obtains information regarding the account, including a person's name associated with the account, using the received information. It also accepts a name from a specific consumer in the vicinity. At this point, it determines whether the name accepted from the specific consumer and the name associated with the account are identical. If it determines that the two names are identical, it checks-in the consumer to the store.

Abstract: Techniques and arrangements for providing kitchen display interfaces with in flight capabilities. In some examples, a kitchen display system presents, via a kitchen display user interface, a first order ticket associated with a first transaction between a merchant and a first customer and a second order ticket associated with a second transaction between the merchant and a second customer. The kitchen display system can then generate a list of items based at least in part on the first order ticket and the second order ticket. In some examples, the list of items includes items from the first order ticket and the second order ticket that are in an in progress state. After generating the list of items, the kitchen display system presents the list of items via the kitchen display user interface. In some examples, the kitchen display system further sends the list of items to another merchant device.

Abstract: Techniques and arrangements for facilitating synchronization of open tickets between electronic devices using application programming interfaces. In some examples, a system may provide an application programming interface (API) for generating open tickets to a first electronic device and receive, from the first electronic device using the API, cart information indicating one or more items. The server can then generate an open ticket based at least in part on the cart information and send data associated with the open ticket to a second electronic device. In some examples, the data includes the one or more items. In some examples, the first electronic device can add additional items to the open ticket via the API and/or the second electronic device add additional items to the open ticket by sending data associated with the additional items to the server.

Abstract: An aggregating server obtains information about a method of payments by a customer and aggregate all instances of payment by that customer with respect to one or more merchants. That is, the server can associate various methods of payment at a merchant with the same customer (e.g. credit card information, information associated with a digital wallet application payment, device identifier along with geo-fence data, etc.) Thereafter, information at the server regarding frequency of visits, money spent, menu preferences, etc. can also be shared with the merchant in order to provide information for increasing customer satisfaction during further visits by the customer. Also, the server can determine whether the customer qualifies for a loyalty or discount programs based on past visits.

Abstract: A method and apparatus is disclosed for protecting electronic devices from security breaches (e.g., in the form of DPA attacks) by managing input/output (I/O) pin states. The technique is particularly useful in financial applications in which data security related operations, such as those involving cryptography, are performed by payment card readers, and the power supplied to drive the operations are measured and analyzed by attackers to extract sensitive information. The technique prevents any external device from measuring the operation power by disabling the I/O pins. The I/O pins are set to a logic low at any given time a data security related operation is performed. As a result, no communication with the external environment is possible during the data security operation, and external power measurements by DPAs are prevented.

Abstract: Techniques and arrangements for creating a data structure for recording interactions between a first user and a second user for interactions to occur at a specified future time. The techniques and arrangements include facilitating annotation of the data structure. At the specified future time, the created data structure may be used to track items ordered, track tenders used to pay for items, and the like.

Abstract: In some examples, a merchant device at a point of sale (POS) location may present information to a merchant in a first language preferred by the merchant, and may present information to a buyer in a second language preferred by the buyer. The merchant device may switch between the different languages in response to detecting a change in the physical orientation of a display. For instance, in a first orientation in which the display is viewable from a merchant direction, the merchant device may present information in the language preferred by the merchant. When the orientation of the display is changed to a second orientation in which the display is viewable from a buyer direction, the merchant device may present information in the language indicated to be preferred by the buyer. Various techniques may be used for determining the preferred language of a particular buyer.

Abstract: A device may include a physically unclonable function (PUF) source that has at least one fuse embedded in the device. The PUF source may be responsive to an input for transmitting a signal through the fuse and providing a PUF value based on a measurement of such signal. The device also has circuitry that is configured to modify the fuse by transmitting a signal of sufficiently high current or voltage through the fuse to change its resistance, thereby changing a response of the PUF source to the input.

Abstract: In some examples, a first device of a first buyer may receive a selection of a first item offered by a selected merchant. The first device may determine whether any second devices are within a threshold distance of the first device. Based on a second device being within the threshold distance, the first device may send, to the second device, a communication for creating a combined order. Receipt of the communication may cause the second device to present, to a second buyer, an interface for creating a combined order. The second buyer may use the second device to select a second item to order from the merchant. At least one of the first device or the second device may send combined order information to a service computing device, which may send the combined order to the merchant and schedule a courier to deliver the ordered items to the buyers.

Abstract: Some examples include determining a plurality of motion pattern readings detected by an electronic device in conjunction with entry of a passcode on the electronic device, such as for authentication of a transaction. The passcode may be entered as a sequence of tactile presses on the electronic device, and the detected motion pattern readings may be indicative of movements of the electronic device when the tactile presses occur. Based at least in part on the motion pattern readings, a plurality of locations corresponding to the tactile presses may be determined. Further, based at least in part on the determined plurality of locations, symbols for the passcode may be determined. In some cases, a process for authenticating the transaction may be initiated using the determined passcode.

Abstract: A payment terminal such as a payment reader may receive and form electrical connections with an electronic transaction card such as an EMV chip card. The payment terminal may provide a clock signal at a rate that exceeds a specified rate for the EMV chip card. The payment terminal may transmit messages to the EMV chip card and monitor receive messages at a data connection. The payment terminal may determine that the clock rate is excessive based on a timeout of a receive message, an error rate of a receive message, or a receive message indicating that one of the transmit messages was not received by the EMV card. The payment terminal may reduce the clock rate to a rate that is below the specified rate for the EMV chip card.

Abstract: A payment terminal has a clock management unit for providing clock signals to components of the payment terminal. The payment terminal also has a wireless communication interface for communicating wireless signals. A processing unit of the payment terminal may monitor clock signals provided by the clock management unit and determine a phase and frequency difference between a clock signal provided to a component producing RF noise and a clock signal provided to a wireless communication interface of the payment terminal. When RF noise present in the received wireless signal falls below a threshold, the processing unit may sample the received wireless signal.

Abstract: A payment terminal has a clock management unit for providing clock signals to components of the payment terminal. The payment terminal also has a wireless communication interface for communicating wireless signals. A processing unit of the payment terminal may monitor operation of a wireless communication interface of the payment terminal and, when the payment terminal is communicating wirelessly, modify an initial clock signal provided to one or more components of the payment terminal that emit RF noise to modify a frequency at which the RF noise occurs. When the payment terminal is no longer transmitting, the processing unit may provide the initial clock signal to the RF noise source.

A first subset of the firmware instructions is associated with transaction processing modules. Each of the transaction processing modules comprise position independent code and are located in a distinct section of memory from a second subset of firmware instructions and the position independent code associated with each of the other of the transaction processing modules.

Abstract: A circuit board is protected by being enclosed in a security housing that includes conductive tamper traces running along its interior surface, the conductive tamper traces being a housing portion of a tamper detection circuit. The tamper detection circuit also includes a board portion that detect tampering with the tamper detection circuit by monitoring voltages at monitor nodes along the board portion. The board portion of the tamper detection circuit is connected to the tamper traces via multiple connector pieces. The connector pieces can be held in place by board connector piece holders affixed to the board or housing connector piece holders of the housing. When tampering is detected, it can be localized based on voltages measured at multiple recesses along the housing. The tamper detection circuit can be arranged in a wheatstone bridge layout for environmental tolerance. The circuit board's functions/components can be disabled if tampering is detected.

Abstract: Methods, systems, and computer program products for a digital wallet for a group of people.
