The essentials

The essentials

The Vortex-Soft proposal for ERK+.

ERK+ demands seven technical capabilities that are rare in West Africa: sealed roles, Mobile Money, live video, offline mode, an encrypted vault, performance on 3G/4G, and an architecture open to your V2 and V3.

We have already shipped all of them. One is in production: eCampus, public and verifiable right now.

Under construction

We build ERK+ in front of you — floor by floor, demo every two weeks.

Method: ship, don't promise

Every two weeks, a working version is deployed to an environment reserved for you. Each block is testable end to end across your three client journeys. Nothing is discovered at acceptance.

What we deliver

  • The 19 modules of the specification, from authentication to warranty
  • Three applications: web, iOS and Android (published to the stores), admin back-office
  • The required integrations: Mobile Money & card, live camera, e-signature, push / SMS / e-mail notifications
  • As a bonus: the ERK+ desktop app for Windows, macOS and Linux
