We are planning to introduce an e-commerce system soon. When that is implemented, you will be able to purchase credits which can be used to then pay for the certificates you issue. Currently we work on a somewhat manual system - when you are going to be running a course, ask one of the project administrators to load credits for your organisation. Then add attendees to your course (you can do this individually or in bulk by providing a CSV file). Once you have issued certificates for each attendee you can issue certificates. The process of registering an attendee and issuing the certificate is separated so you need only issue certificate to those that pass your course. Each attendee will receive an email with a link to a downloadable copy of the certificate. The certificate includes a unique number which is allocated to each certificate and a unique link that they can provide (for example in their CV) to verify that they have indeed completed the course. This mechanism should help to prevent fake certificates. Course conveners should upload a digital signature to their profile. This is embedded into the certificate together with the digital signature of the project leader (who needs to set this in the project profile options page).
