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 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.

A point of sale system includes a merchant terminal and a customer terminal. The merchant terminal is configured to display a user interface (UI) window on the merchant terminal. The UI window on the merchant terminal displays a merchant-specific version of a screen displayed on the customer terminal. The merchant terminal receives updates from the customer terminal regarding the status of the payment portion for a transaction. The merchant terminal can provide an input to the UI window which is sent as a message to the customer terminal. Control of state for the point of sale system is shared such that when the system is in a first state, the merchant terminal is the state control terminal, and when the point of sale system is in a second state, the customer terminal is the state control terminal and has control of state for the system.

A tamper-resistant or tamper-evident keypad device for use in secure transactions. The keypad comprises multiple security mechanisms to prevent tampering to the device, and thus access to users' private information. The keypad is made of resilient materials and contains a tamper-resistant collar for housing the keypad's connector interface. The keypad comprises a multi-layered printed circuit board with at least two internal security-shield layers comprising switch trace protection, as well as additional security layers for tamper protection. The keypad comprises a silicon-rubber keypad actuator that engages tamper switches on the flexible security circuit. The keypad comprises metal discs mounted on the front or rear face of the flexible circuit and an optional dome layer.

Biometric features are derived from security data associated with a subject. The security data is obtained from a security device. A biometric value is calculated from the biometric features. The biometric value is anonymized to an identifier associated with the subject. The identifier is integrated with event data associated with a security system. In an embodiment, the security device is a Personal Identification Number (PIN) pad integrated into a transaction terminal, the security data is fingerprint data, which is read from a finger of the subject placed on a fingerprint reader integrated into the PIN pad, and the biometric value is a PIN calculated from fingerprint data during a transaction at the transaction terminal. In an embodiment, the security device is a security camera, the security data is a secure video stream, and the biometric features are facial features of the subject in the secure video stream.

A transaction terminal device includes an orientation detecting unit that detects the orientation of an information processing device with respect to the orientation of gravity, and an information processing unit that displays a work screen of work categories on a display unit based on display attributes for changing of the orientation of the information processing device configured for each of the work categories. When the display attributes are permitted for rotating the work screen based on the changing of the orientation of the information processing device, the information processing unit displays the respective elements constituting the work screen in the position/orientation based on the detected result by the orientation detecting unit. When the display attributes are prohibited from rotating the work screen, the information processing unit displays the respective elements constituting the work screen in the fixed position/orientation independent from the detected result by the orientation detecting unit.

When an information processing apparatus connected to an external device via a network respectively displays an operation screen on an operation unit provided thereto and on the external device, the information processing apparatus changes display of a touched key with highlighting or without highlighting according to whether confidential information such as a password is entered. Depending on the entry on the operation unit, whether to display a character on the operation unit or not is determined. If the character is to be displayed, the highlighting of the character is not performed. If the character is not to be displayed, the highlighting of the character is performed.

A keypad overlay for credit card machines includes a main panel, a lateral wall, a connector wall, a plurality of button receiving features, a first attachment hole, and a second attachment hole. The connector wall and the lateral wall are perimetrically positioned around the main panel. The connector wall is terminally connected to the main panel. The lateral wall is terminally connected to the main panel. The plurality of button receiving features is integrated onto the main panel. The first attachment hole and the second attachment hole are oppositely positioned of each other along the connector wall. The first attachment hole traverses through the connector wall. The second attachment hole traverses through the connector wall.

An input device has a support that has a user control area and that has a coupling area for coupling an object to be monitored to the input device; an electromechanical transducer structure that is coupled both to the user control area and to the coupling area; and a control apparatus that uses the electromechanical transducer structure to implement a user control function of the user control area and further to implement mechanical integrity monitoring of the object to be monitored and/or the support.

Systems and methods are disclosed for obfuscating entry of sensitive data at a mobile device, which may be infected with a rogue application configured to steal the sensitive data. One method comprises detecting a prompt for a user to enter sensitive data at a mobile device, and activating one or more of an audio speaker and a vibration motor of the mobile device. The activation of the one or more of the audio speaker and the vibration motor is terminated in response detection conclusion of the user's entry of sensitive data the mobile device.
