Please do not use this service, they are scam, will collect your documents and then ask for others. Will make excuses for not applying for a card.
I am not sure what they do with your documents.
I am complaining about them to NDSL.
Their customer service is worse than govt banks, they don't reply more than once a day.
I think their intension is to make fake identities, by collecting original identities.
Please dont give them any documents.
