Does it work for digital prescriptions?
Yes. A prescription signed with an ICP-Brasil certificate is legally valid and pharmacies can check it on ITI's official validator (ITI is the federal agency that runs ICP-Brasil).
Which storage is best if I work in several clinics?
Cloud: you sign from your phone, on any computer, without carrying a token.
How long does it take?
The certificate is issued immediately once validation is approved. Customers who buy in the morning with their documents in order are usually signing the same day.
Do I need to travel to Extrema?
No. Video validation serves all of Brazil. In-person service in Extrema, MG, is there for those who prefer it, for those who only have a digital ID, and for cases where the rules require being present.
Which should I choose: A1, A3 or Cloud?
If you issue invoices from software installed on a single computer, A1 does the job and costs less. If you sign from your phone, travel or use more than one computer, Cloud saves you headaches. An A3 token makes sense when some system requires physical media.
