Question about signing up for NETeller. This the right place?

[Curtrosity]

I registered for NETeller and got an e-mail saying they couldn't match my SSN. I called them and gave them my full SSN and the operator said they still couldn't match. He then said I need to take a picture of the front and back of my SS Card and my I.D. and e-mail it to them. Has anyone every experienced this? I don't feel totally comfortable e-mailing those things. Just trying to be certain about what I'm doing.

Thanks
