Techniques described herein are directed to, among other things, utilizing a self-centering user interface to receive information associated with a transaction. For instance, a computing device may receive a first input at a first location of a display. The computing device may then determine a positioning for the user interface, where the user interface may be substantially centered about the first location. In some instances, the computing device may display the user interface using the positioning. The computing device may then receive a second input corresponding to swipe from the first location of the display to a second location of the display. The computing device may then determine a symbol included in the user interface based at least in part on the second input. In some instances, the user interface includes a keypad for entering a personal identification number associated with a payment instrument.

A mobile device is provided that includes biometric sensor(s), and a processor that causes the biometric sensor(s) to acquire a physiological marker of a user, and identify and authenticate the user. The processor sends a message to an authentication server that indicates the user is authenticated, and receives a response from the authentication server that includes a unique authentication code. The processor receives selection of a thereby selected over-the-counter (OTC) drug, and communicates with a point-of-sale (POS) system with contactless payment capability. The processor sends a purchase message to the POS system that includes the unique authentication code, an identifier of the selected OTC drug, and payment information. And the POS system communicates with the authentication server to validate the unique authentication code, and with an authorization server to authorize payment for the selected OTC drug based on the payment information.

Disclosed herein are system, method, and apparatus for detecting a skimmer via a vibration sensor on a transaction card. The method includes receiving, at a server, from a user equipment, vibration information recorded by a transaction card in response to an execution of a transaction at a point-of-service (POS) terminal of a plurality of POS terminals using the transaction card. The vibration information may be recorded by a microphone or an accelerometer on the transaction card while the transaction card is swiped through the POS terminal or inserted into or removed from the POS terminal. The method includes determining, at the server, a state of the POS terminal based on the received vibration information and in response to a determination of the state of the POS being compromised, sending to one or more stakeholders of the transaction a warning message containing the POS terminal information including the POS terminal's state.

Provided are methods, systems, and computer program products for verifying a card image file. A system may include at least one processor programmed or configured to parse a card image file to determine card data represented by the card image file, generate a plurality of simulated payment transactions based on the card data, each simulated payment transaction including simulated transaction data, issue a plurality of commands to the payment device emulator, the plurality of commands based on the simulated transaction data for the plurality of simulated payment transactions, receive a plurality of command responses generated by the payment device emulator based on the plurality of commands, and verify the card image file based on the plurality of command responses and the card data.

A controlled dispensing fixture including a display screen, a scanning device, and one or more processors is configured to: obtain via the display screen or remote scanner a selection of one or more controlled products; update a user interface on the display screen based on the selection; determine whether the one or more controlled products meet a purchase limit associated with the one or more controlled products for dispensing; obtain via the scanning device consumer identification information; determine whether the consumer identification information meets an age threshold and/or an identity requirement associated with the one or more controlled products; and in accordance with a determination that (i) the one or more controlled products meet the purchase limit for dispensing, and (ii) the consumer identification information meets the age threshold and/or the identity requirement, transmit a dispensing instruction to the dispensing fixture to dispense the one or more controlled products.

A transaction card construction and computer-implemented methods for a transaction card are described. The transaction card has vector formatted visible information lasered onto its surface. In some embodiments, systems and methods are disclosed for enabling the sourcing of visible information using a scalable vector format. The systems and methods may receive a request to add a first plurality of visible information to a transaction card and capture an image of the first plurality of visible information. The systems and methods may also map the image to a bounding box and convert the mapped image into vector format. In addition, the systems and methods may provide the converted image to a laser machine.

In a method for advanced identification of a customer, a customer may remotely place an order, intending to later go to a store to pick up the ordered item. The store may have a pick-up area (e.g., at the back of the store) where the customer can go to pick up the ordered item. To save the customer time, the customer may be identified when she enters the store so that an employee can obtain her ordered item and have it ready to pick up by the time the customer walks through the store and arrives at the pick-up area.

A multimode system for receiving data in a retail environment includes: a secure input module for receiving high security input and low security input from a customer, the high security input to be communicated by the secure input module in cipher text, and the low security input to be communicated by the secure input module in plaintext. The multimode system is adapted to operate in a high security mode and a low security mode. The multimode system is adapted to enter the low security mode upon detection by the multimode system of a security breach condition. In the high security mode, the secure input module accepts low security input and high security input. In the low security mode, the secure input module accepts the low security input and does not accept the high security input.
