The tanJack optic CX is the only known device me about a cover flap and is particularly small and handy. Of course, the device of the present current HHD version 1.4, which is important to make it work with all banks corresponds. The built-in display with two lines is read blickwinkel stable and easy. The highlight is the already mentioned built-in cover plate which covers the unused keys in daily use. Because these buttons do you actually need only to set up and very specific special functions such as the reading of GaldKarten. The flicker detection is better than in older or other TAN generators that I was allowed to use already. Although I completely shut usually the device detects the brightness of the screen of my monitor to flicker code still without problems. During my two generators of Kobil have failed after a short time, me my three tanJack optic CX accompany been around for about half a year without any problems. Incidentally, you can use multiple generators, it must be taken only the bank card.
Here are a fundamental excursus on TAN procedure and why you should use the chipTAN the tanJack: In the beginning there were only simple TAN lists and for every transaction you have entered any TAN. After criminals developed the Phishing for TAN and bank accounts plundered, the banks have converted to iTAN. Here you have to enter a specific TAN for authorization. The problem is that criminals can swindle by a man-in-the-middle attack, or by means of a Trojan horse on the computer of bank customers when desired by the user transfer a certain iTAN and thus actually authorize their transfer to plunder the account can. Therefore iTAN is unsafe for years. Then the banks have introduced mTAN or smsTAN. The user receives a text message with the transfer data to control and of course the TAN. The problem is, criminals can no knowledge of the phone owner get a multiSIM or intercept the SMS via SS7 Intercept at network level, thus reach the TAN without the bank customer noticed something. The same problem arises from Trojan on smartphones and of course also applies to the pushTAN process on smartphones. Hence the smsTAN and pushTAN process is burned or unsafe.
As a relatively safe applies currently chipTAN process for the ReinerSCT tanJack is, at issue here. If online banking is something to authorize such a transfer, online banking generated a flicker code and displays it. The user then holds his chipTAN generator to the computer screen. About the Flicker Code of TAN generator receives the destination account number and the amount notified, so that this data does not have to be typed. This data is displayed to the user on the display of the TAN generator to control. Confirmed the target user account number and amount, these data are rolled together with a secret key of the inserted bank card to a TAN. This indicated TAN is a user in online banking. If this produced chipTAN an impostor in his hands, it is worthless, because it applies only to the specified target account number on the specified amount! The security stands and falls with the control in the display, the TAN generator and confirmatory data.
