Paddle has no excuse for collecting selfies, they are providing services to businesses that can be verified in more humane and secure ways, such as an electronic signature.
Verifying people with selfies is a degrading and insecure practice, especially when you encounter Onfido during the installation process of a bank's app that you already have an account with, opened in person at a local branch in the EU. This bank also asks you to create a video of yourself and submit your speech to configure their mobile banking app. I'm sure the data will be useful for someone when Onfido eventually gets hacked, or just sells your biometric data.
My hope is that biometric data collection for online account verification will become illegal once all EU member states have intoduced electronic IDs which have an NFC chip. The verification should consist of a person holding their ID next to their phone, and the online service would only receive the minimum amount of personal data to complete the verification.
