For my work I some times have to sign a pdf document (contract for example). Heretofore I had to print that document, sign it with a pen and then scan it to make it digital again. Nowadays I use a digital signature service. This saves me time, is more sustainable (less paper) and I do not need a scanner for it anymore.
I see more and more digital signatures services this days. But most of them only offer a service that place a image of your signature on the pdf document. In my opinion, that is not a fully-fledged digital replacement of the physical signature.
Self I use a service (eSGN from Digidentity) that signs the document with a digital certificate and gives some guaranty about the person that have sign the document. And that last point makes this service valuable but normally also more expensive. This because the digital signature company have to verify the identity of the person and must maintain a more extensive administration.
Bunq already have verify all of his users. So they don’t have to make this extra effort and can maybe offer this (extra) service for a small fee. I think that especially for business users this can by a very handy service.
There is no need for extra buttons in the app. When you select a pdf file on your smartphone and open the file with the bunq app, there will popup a option to digital sign the document. After a confirmation, the document will be singed. In the transaction overview a new transaction will appear with all the information about the document and the digital signature. The document can be download through a button in the transaction details.
In de bunq web app there is maybe some more space available. It would be great if you could upload a document here and see some kind of archive of the signed documents.
I’m aware of the fact that this service would probably not directly matches with the core business of bunq. But on the other hands, bunq is set up to make financial transactions easy and fun. Why not also making signing documents easy and fun. It can be a unique selling point and can attract some attention. Especially with business customers.
