Verification costs 10-50 USD (depends on region). Tokenholder can divide the half of it between him and a new user, who needs a verification. He should transfer tokens into stack on his backoffice. After that he will receive a refferal link. Tokenholder can place it in some internet resources (website, social networks etc). When user (who needs a verification) follows this refferal link and pays for a verification ($10-50), he receives a discount and the tokenholder receives the rest part of the half of verification price. The tokenholder should decide (and fix it in his stack) in what proportion the half of the verification price will be divided between him and the user. The stack is a personal cabinet into which the tokenholder placed his tokens and generates a unique link with its unique price at which customers can get a special price different from the base price
