Paying with Tradebank is no different than paying with any other debit card. It is always the responsibility of the seller to obtain the authorization; it is how they are paid. The authorization can be obtained via www.mytradebank.com or Tradebank’s mobile pay App when the funds are transferred from the buyer’s account to the seller’s. In the process of completing the transaction, the seller should ask the buyer for their Tradebank debit card in order to obtain the buyer’s 16 digit account number and verify the purchaser is a valid Tradebank cardholder.
