用这个还需要M-TAN和CHIPTAN吗？

没用过，不过看了下介绍。就是一个优盘，用的时候插在电脑上，转账的时候按一下优盘上的按钮。

拷贝了一段，看看吧

In a similar way to the mobileTAN and chipTAN comfort procedure, Postbank sends the transaction data such as the recipient’s account number and the amount to the USB device connected to the customer’s PC. After the USB device has received the data, it shows the recipient’s account number and the transfer amount on the display of the USB device. The client must check the accuracy of this data before approving the payment transfer by pressing the USB button. Pressing the button causes the chip inside the USB device to generate a digital signature that replaces the client’s personal signature. As with all signature procedures, the exchange of data between the device and Postbank is fully encrypted. The client computer serves here merely to provide electric power and access to online banking.
