Reading off barcodes, checking and verifying transaction-related details, entering TANs in order to release transactions.
End-users complete an online form and send it to the application server. In order to approve the data, the server causes a barcode to be displayed. Once the end-user has inserted their banking card (Smart Card) into TAN Optimus and held the reader in front of the monitor, the details will be displayed. The user approves the transaction-related data (on the offline device’s display) and accepts the generation of a one-time code.
TAN Optimus Comfort allows for reading transaction-related data from PCs, tablets or Smartphones and thus prevents man-in-the-middle or man-in-the-machine attacks. The transaction-related TANs ensure the scanned barcode to be generated by the right server and to be valid for this specific transaction only.
