It is Uanataca's service to integrate the electronic signature in business and organisational processes for any type of document or transaction guaranteeing its integrity and authenticity. By integrating the signature API into your BMP, ERP or any application, you can have your employees, customers, suppliers or partners sign electronically without losing the current user experience. For the interactive signature, Uanataca digital certificates issued centrally in the SignCloud system are used, which guarantees the exclusive control of the signature key to its holder.
