TANs often function as follows:

# The bank creates a set of unique TANs for the user.<ref>{{Cite web |title=Transaction Authentication Number (TAN) |url=https://fraud.net/d/transaction-authentication-number/ |access-date=2023-12-14 |website=Fraud.net |language=en-US}}</ref> Typically, there are 50 TANs printed on a list, enough to last half a year for a normal user; each TAN being six or eight characters long.

# The user picks up the list from the nearest bank branch (presenting a [[passport]], an [[ID card]] or similar document) or is sent the TAN list through mail.

# The password (PIN) is mailed separately.
