Case Study: Leading E-commerce and Payment Product Company lands global fast-food client and boosts QR code speed with Altoros

Leading E-commerce and Payment Product Company - Customer Case Study

The customer, a provider of e‑commerce and payment products for U.S. and global markets, needed flexible development resources to deliver restaurant‑ and bank‑branded mobile payment apps on tight timelines. They engaged Altoros to customize their mobile payment solution (iOS app work using REST API and Paydiant SDK) to enable pay‑ahead ordering, real‑time account synchronization, cardless ATM access and faster QR‑code reading while ensuring strong transaction security.

Altoros implemented account integration and single sign‑on via REST API/Paydiant SDK, added multi‑factor authentication, memory‑clearing to prevent data leakage, and replaced QR libraries with ZBar/ZXing to speed scanning. The work helped the customer secure a large global fast‑food client, produced apps installed by thousands of users across dozens of U.S. restaurants and banks, significantly improved QR performance and user satisfaction, and set the stage for further international expansion.
