It is the Uanataca service for the electronic signature of large quantities of any type of document or transaction guaranteeing its integrity and authenticity. To use it you can do it in two ways, using a desktop application that indicates the signature format, the digital certificate to be used, the location of the documents to be signed and the location of the signed documents. The second is through a simple integration with a high-level API that will allow you to integrate the service into your own applications. You will not need to buy or maintain or update electronic signature systems or applications. You will only pay for what you consume. If you are going to make less than 10 million signatures a year, it will be very profitable.
