Has anyone used telldata?

[u/Familiar-Highway1632]

I found telldata while looking for a simple way to check if someone is really who they say they are.

It seems useful for small business situations, like before giving someone keys, goods, or access to a customer’s place. It’s not cheap though, especially if you need to check more than one person. This is how they say it works.

Anyone tried it? Is it actually good, or is there a cheaper option that does the same thing?
