Overview
The project
in context.
RewardMe automatically rewards everyday shopping without requiring manual receipts or barcode scanning. StartxLabs built the mobile application and secure card-linking integration that matches credit and debit card transactions against partner merchant offers to instantly deposit cashback into user accounts.

The challenge
What was
blocking progress.
Legacy loyalty programs forced shoppers to carry plastic membership cards or upload receipts manually, leading to low retention and forgotten rewards.
01
Card transaction matching required low-latency webhooks from card networks
02
PCI-DSS security compliance was strictly mandatory for handling tokenized payment data
03
Users needed instant notification when cashback was earned at a merchant
04
Merchant partners required an analytics dashboard to track return on ad spend
