Comfort Very good TAN generator as a substitute for Optimus

After our two Optimus comfort of cooperative banks were broken almost simultaneously after several years of use - they showed despite full batteries no more reaction when plugging various debit cards - I ordered the ReinerSCT Tan Jack.

I can currently about the longevity of the production say anything yet because we have only a couple of days in use, but the TanJack work with us 10x better than the Optimus comfort devices, ie, the Tans are generated much faster, since the transmission of the code has not always worked super fast and without problems. The Optimus comfort devices, there have been times problems depending on the screen and the lighting.

Whoever has the choice should definitely grab this device. 5 stars, no other words necessary.
