Transaction Authentication Number (TAN)

Transaction Authentication Number (TAN) is a one-time-use, secure code used to authenticate online financial transactions. It is usually generated by the bank or credit card issuer and sent to the customer via email or text message. The customer then must input the TAN code into the website or app where they are making the purchase to complete their transaction.
