The tanJack® deluxe cannot be attacked online, as it does not require an internet connection for its use. Premium online banking: Not only is security at the highest standard, but user-friendliness is also state of the art. The graphic codes from chipTAN QR and Sm@rt-TAN photo are captured lightning-fast in any position and on all devices. The data from online banking transactions and the TANs are clearly displayed on the large screen. Of course, the tanJack® deluxe also has a card slot for your bank or savings bank card for secure TAN generation. Two-factor authentication: Almost all leading online platforms offer the option to log in with two-factor authentication (2FA). This is usually done with an additional 6-digit code. The tanJack® deluxe securely stores the electronic keys for these logins in its hardware and generates TOTP one-time passwords with high accuracy every 30 seconds. The Federal Office for Information Security (BSI) explicitly recommends the use of two-factor authentication.
