AI Technical Summary

Technical Problem

Individuals lack control over spending behavior when lending payment instruments to others, and existing technologies do not allow secure, user-defined limitations for temporary use of payment credentials.

Method used

A first device generates a sub-payment token with user-selected limitations, which can be directly communicated to a second device without a backend server, enabling secure and controlled lending of payment credentials for contactless transactions.

Benefits of technology

Enables faster and more secure lending of payment credentials with user-defined restrictions, enhancing control and security in contactless payment scenarios.

Abstract

A system and method are described that allows a first client device to authorize a second client device to use a payment token for contactless payments, where the payment token is authenticated for use by the second device with restrictions set by the first device. In one embodiment, the system comprises a computing device including a secure element. The system also includes machine-readable instructions that, when executed by a processor, cause the computing device to at least receive instructions for generating a sub-payment token and receive a selection of key restrictions for the sub-payment token. An application stored in the secure element is invoked to generate the sub-payment token based on the key restrictions. The sub-payment token is received and includes a sub-payment key and an application transaction counter range. The sub-payment token is transmitted to the second computing device over a wireless communication session.
