The company E-Rasta specializes in creating applications using artificial intelligence technology. The Photko app is used on smartphones for solutions that aim to provide a quick and easy solution for capturing biometric photography of a real face with depth (liveness check). The photo is later used for an identity document that complies with all biometric and other legal requirements for photographs on identity documents. It alerts the user in real-time with simple facial corrections such as straightening your head, opening your eyes, looking straight, incorrect background, etc...

The second app developed by the company is Verified by Photko. The app enables artificial intelligence to carry out registration, eSigning, and other trust services. In the process of using it, the user captures and validates firstly their ID and then their face with the help of a liveness check. It allows the customer to use a service from their phone or tablet. It is not necessary to physically visit the company’s office to sign or confirm the contract.
