CardBazaar

A multi-vendor gift card marketplace for web, iOS, and Android with automated balance verification and flexible payment flows.

Client request

What the client needed.

CardBazaar needed to evolve from a limited single-vendor gift card store into a scalable marketplace where independent sellers could register, list inventory, and sell gift cards. The scope also included a much larger catalogue, automated balance verification, cryptocurrency payments and withdrawals, and new native mobile apps.

Our approach

What we did.

We rebuilt the platform end to end: a modern web marketplace, native iOS and Android apps, marketplace operations backend, seller management, third-party balance verification, eCheck services, and cryptocurrency payment and withdrawal flows.

Marketplace transformation

From a single-vendor store to an open marketplace.

The original business could only sell its own limited inventory. We rebuilt the product around independent sellers and a significantly broader gift-card catalogue.

Seller registration and marketplace onboarding
Gift-card listing and inventory-management workflows
Multi-vendor selling model for independent merchants
Expanded catalogue beyond the original 5–6 card types
Responsive web marketplace with redesigned user experience

Transaction infrastructure

Verification and payment flows built around gift cards.

The marketplace needed reliable ways to validate card value and support more flexible transaction methods across multiple providers.

Automated balance-verification integrations
Third-party API connections for card data
Web-crawling services for providers without suitable APIs
eCheck selling and withdrawal workflows
Cryptocurrency payments and withdrawal functionality

Web and mobile delivery

One product ecosystem across customer devices.

We developed the operational backend and customer-facing products together so marketplace, seller, and payment workflows remain consistent across channels.
