The article describes how the digital wallet called Paze has been created by JPMorgan to help with e-commerce cart abandonment. The Paze wallet involves a product known as a "Bank-to-Wallet" ecosystem, which allows for an automated way to provision e-commerce retailers through automated provisioning services. There are over 150 million pre-loaded payment cards that use the platform. In addition to describing the technical implementation and architecture of the underlying backend microservices for the Paze wallet (Java 21 and Spring Boot), the paper will discuss how the wallet receives bank-verified funding sources (i.e., payment cards) through two types of services, known as Bulk Provisioning and Auto-Provisioning Services. These services will allow for the management and secure population of the wallet with bank-verified funding sources. There is also an associated Business Rule Engine that was created for use with the Paze wallet and uses the Drools rule engine in order to decouple variable eligibility logic from core transactional processing; thereby allowing for real-time updates without requiring system downtime. The transition from conventional on-premise technology to a cloud-native AWS architecture has been implemented successfully, providing a 30% increase in operational efficiency and maintaining a 99.99% system uptime. As a by-product of the process of implementing network tokenization, the paze wallet replaces sensitive 16-digit credit/debit card numbers with secure tokens (i.e., preventing the storage of card numbers within the Paze application) preventing credit/debit card fraud in connection with e-commerce transactions. Based on these metrics, it has been demonstrated that the average time to complete a checkout using the Paze wallet is less than 51 seconds, effectively addressing the 70% U.S. e-commerce cart abandonment concern.
