“Since I installed and started using the Multicert ID app, it has become my only way to sign digitally. The app offers the mobility, security, and efficiency required to meet today’s market demands, making it an indispensable tool in my daily routine. In my role, which is mainly commercial and managerial, I’m rarely in front of a computer. My phone has become my ‘desk,’ where I have all the collaborative tools I need.”
“A professional certificate linked to the Multicert ID app seemed to be exactly what we needed to digitize our processes. (…) Before, when I was away from the office, these processes would be left pending, and once I returned, I had a pile of documents to sign. In that sense, for me, the Multicert ID app was a relief. Because nowadays, regardless of where I am, if there’s a contract to sign at that moment, I now have this reliable, trustworthy method (…) it’s so quick and easy that even non-urgent matters get done right away. It’s resolved instantly because it takes me only a few seconds to sign.”
