The present technology includes a point of sale system for facilitating interactions between a customer and a merchant in a payment transaction, and for communicating with a payment server to complete the transaction. The point of sale system includes a central processor, a payment object processor, a payment object reader interface, and a a touch screen. The central processor is configured to execute an operating system and to execute a transaction engine configured to manage payment transaction specific functions of the point of sale system such as to control the touch screen to display payment transaction information on the touch screen, and to control the payment object processor to control the payment object reader to receive payment object information.

The present application discloses a payment information processing method, apparatus, device, and computer readable storage medium. The payment information processing method includes: obtaining an environment image collected by a mobile acquiring device, in response to an acquiring request sent by the mobile acquiring device; determining a payment environment confidence level of the mobile acquiring device according to the environment image, under a condition that the mobile acquiring device obtains payment card information; determining a payment information processing result according to the payment environment confidence level.

A system and method of setting and charging a fixed donation amount provides a convenient contactless payment for donations. The system includes at least one portable donation terminal and at least one administrator personal computing (PC) device. The portable donation terminal is communicably coupled to the administrator PC device. An administrator may be a cashier, a clerk, a clergy member, and so on. The method begins by outputting a fixed charging amount with the portable donation terminal. Donation information is received through the portable donation terminal. The donation information is processed for the fixed charging amount. An administrator is prompted to generate a receipt of the fixed charging amount for the donation information. At least one remote server may also be communicably coupled to the administrator PC device in order to provide a reference identifier for the receipt. The receipt is outputted with the administrator PC device.

Systems, methods, and articles of manufacture to securely share data stored in a blockchain. A contactless card may receive a request to provide a data element from a device. An applet of the contactless card may encrypt the data element and a wallet address. The applet may generate a signature for the request, and transmit, to a mobile device, the signature and the encrypted data. The mobile device may transmit, to a verification service, the signature and encrypted data. The verification service may verify the signature based on a public key. A node in a blockchain may generate a block in the blockchain, the block comprising indications of the verification of the signature, the requested data element, and the wallet address. An encrypted data element corresponding to the data element may be decrypted using a public key. The device may receive the decrypted data element from the wallet address.

Various embodiments for contextual tapping engines. For example, an application executing on a computing device may authenticate credentials associated with an account and detect a tap of a contactless card to the computing device. The application may receive, from a communications interface of the contactless card, action data used to determine an action associated with the tap of the contactless card to the computing device. The application may determine a context of the application based on a current output of the application. The application may determine, based on the action data, the determined context, and data associated with the account, a first action associated with the tap of the contactless card to the computing device, the first action associated with at least one of the application and an operating system (OS). The application may initiate performance of the first action based on the tap of the contactless card.

The present invention relates to a system and a method for authenticating an electronic money using a smart card and a communication terminal. The present invention provides a system and a method for authenticating an electronic money, wherein the system comprises a smart card and a communication terminal. The smart card takes biometric signature from a user as an input, transmits recognition completion information to the communication terminal when the biometric signature inputted by the user matches the stored biometric signature, receives an update command from the communication terminal, updates the amount of stored balance data, and transmits an update completion message to the communication terminal. The communication terminal is connected to the smart card in a wired or wireless manner, and transmits the update command to the smart card upon receipt of the recognition completion information.

Various aspects of the disclosure generally relate to security for a credit card processing reader. Part of security for a reader is a secure cover having a trace mesh to discourage drilling through the cover. The mesh may be connected to one or more landing areas on the cover. The landing area has electrical pads with trace routing that provides tamper protection for the landing area.

A payment reader and a POS terminal may communicate over a wireless connection. The methods and systems include monitoring one or more parameters corresponding to a payment reader and another device in proximity to the payment reader. The first device, through a set of customized instructions, determines whether behavior of the second device substantially corresponds to the first device, in order to detect suspected hardware or software intrusion associated with the secure first device. On successful detection of a suspected intrusion, the first device generates an alert for a user of the first device if illegal intrusion is suspected by the processor.

A merchant payment system designed for a high-traffic merchant. In an embodiment, the merchant payment system comprises a casing, a mobile computing device, a charging regulator, a payment receiver, and a docking station configured to charge the mobile computing device and payment receiver. The outer casing is configured to house the mobile computing device, a charging regulator, and payment receiver. Additionally, the docking station is configured to charge various mobile computing devices (e.g., a tablet or a mobile phone) housed within the casing. Moreover, the docking station is configured to supply a predetermined voltage and current to the charging regulator which in-turn supplies a first predetermined voltage and current to the payment receiver and a second predetermined voltage and current to the mobile computing device.

The present technology pertains to storing transaction information for transactions with merchants in association with an identifier of a buyer, and transmitting an electronic receipt, including the transaction information to the buyer. The present technology includes a system and methods for associating a transaction card number with the user identifier of the buyer, such that the transaction information can be associated with the user identifier of the buyer even when the merchant does not receive the transaction card number or the user identifier of the buyer.
