Secure Merchant Mobile Payments – Case Studies

Client: National big-box retailer.

Challenge: legacy terminals could not process secure merchant mobile payments during high-traffic Black Friday events.

Solution: A four-developer Smartbrain JavaScript pod rebuilt the payment layer in Node.js with tokenization micro-services and React-based cashier UI. CI/CD pipelines with automated PCI scanning ensured compliance.

Result: 47% latency reduction at checkout, 32% fewer chargebacks and zero downtime during the sale weekend.

Client: VC-backed peer-to-peer payments startup.

Challenge: secure merchant mobile payments had a 6 % failure rate on rooted Android devices.
