Systems and methods for a secure payment terminal without batteries
Various embodiments of the present disclosure provide systems and methods for securing electronic devices, such as financial payment terminals, to protect sensitive data and prevent unauthorized access to confidential information. In embodiments, this is achieved without having to rely on the availability of backup energy sources. In certain embodiments, tampering attempts are thwarted by using a virtually perfect PUF circuit and PUF-generated secret or private key within a payment terminal that does not require a battery backup system and, thus, eliminates the cost associated with common battery-backed security systems. In certain embodiments, during regular operation, sensors constantly monitor the to-be-protected electronic device for tampering attempts and physical attack to ensure the physical integrity. |

Method and system of authenticating a payment transaction using a user device
A method and system for authenticating a payment transaction. The method includes receiving a request for verifying a phone number associated with a Subscriber Identification Module card from a merchant application installed in the user device. Further, obtaining a first key from at least one of a server associated with a manufacturer of the user device and a network server. Furthermore, generating a first cryptogram based on at least one of the phone number and a unique identification value associated with the user device using the first key, wherein the first cryptogram is provided to the server associated with the manufacturer for verification. Upon verification of the first cryptogram, the method includes receiving a second cryptogram from the server associated with the manufacturer, wherein the merchant application provides the second cryptogram and payment transaction details to an issuer server for authentication of the payment transaction. |

Third-party payment interfaces
Disclosed are example methods, systems, and devices for integrating payment API services provided by a service provider computing system with a client application. The client application running on a user device may allow a user to make payments and/or to submit payments for approval and may communicate payment information to a client computing system. If a payment is submitted for approval via the client application, the client computing system may make API calls to the service provider computing system to, for example, submit, view, and/or cancel payments. Payments may be approved by a second user using a second device. The service provider computing system initiates fund transfers for approved payments. Payments may be submitted within the operating environment of the client application without use of an application or website of the service provider. |
