Acuant builds identity verification technology: the software that reads a driver's licence or passport, confirms it is genuine and confirms the person presenting it is really there. Banks, marketplaces and regulated businesses embed it in their own onboarding. CodigoDelSur built and maintained Acuant's iOS and JavaScript SDKs from 2021 to 2024. GBG acquired Acuant in November 2021 for approximately $736 million.
An identity verification SDK is a component other companies' engineers embed in their own onboarding, so it is judged twice: by the developer integrating it and by the fraud team measuring what it catches. It has to read a document in bad light, pull data off the NFC chip in a passport, confirm the face on camera belongs to a living person, and do all of it on the web as well as on iOS, as one flow a user completes in under a minute.

On iOS the work covered document capture with AVFoundation and Vision, NFC chip reading with CoreNFC, liveness detection, and interface work across UIKit and SwiftUI, packaged as XCFrameworks. On the web the same pipeline was delivered in TypeScript with WebAssembly and WebRTC, wrapped in framework-agnostic custom elements so integrators could drop it into any stack. Stack: Swift, SwiftUI, UIKit, Vision, AVFoundation, CoreNFC, TypeScript, WebAssembly, WebRTC, Lit, Jenkins.
iOS and JavaScript identity verification SDKs were built and maintained for more than three years, covering document capture, NFC chip reading and liveness detection on both platforms. The web SDK shipped as framework-agnostic custom elements, integrable into any stack, on an automated release pipeline built for software that runs inside other companies' production systems.
