I dont know well about Jumio, but if I may advise, not only verification using ID-Card so add verification using selfie photos and write some words in the paper. It can help to reduce scammers and spammers
Jumio is currently using netverify, which includes the following verifications :
1. ID Verification
Verify customer IDs in real time
2. Identity Verification
Know the true identity of your customers
3. Document Verification
Capture and verify customer documents with ease
