Tagiy — NFC smart business cards
The studio's own product before the Atiyaf rebrand: a SaaS that turns a physical NFC card into a living profile — tap to share contact, social, portfolio and payment links.
About This Project
Tagiy was a full SaaS product we built and ran end-to-end: hardware procurement, card programming, customer SaaS, and a payments layer. It ran for two years before we folded its technology into the current Atiyaf stack.
The product
Each customer got a set of NFC cards linked to a profile they fully controlled. Tapping the card opened the profile on the recipient's phone — no app install, no login. Profiles supported contact vCards, social links, a portfolio gallery, and a "pay me" button wired to local gateways.
The interesting engineering
- Card serialization tool that signed each card to a profile — replacements rotate the signature so lost cards can be revoked.
- Per-card analytics (taps, regions, hours) surfaced in a small Vue dashboard.
- Theme system with live preview — the core of what is now Atiyaf's Theme Settings.
Much of what now ships as Atiyaf's theme engine, admin scaffolding and modular package structure was proven here first.
Key Features
Challenges
Unknown-to-us hardware vendor quirks on the NFC chips. Two payment gateways with very different webhook shapes. Every customer wanted a different theme by day two.
Solutions
Serialization tool that normalized vendor quirks behind a clean API. A gateway adapter layer — one interface, per-gateway drivers. Theme engine with CSS variables and a live preview (the same engine now powers Atiyaf Theme Settings).
