Hacking E3 Card Reader can now downgrade

Was just skimming through the www.e3-card.com FAQS and came across this question.

Q6: How could I know my E3card Reader is not a fake shit?

I dunno.. It made me laugh

Indeed .

First, every E3card reader contains a global unique ID which could be found in the product label. Enter the ID to the verify text box in our website, soon you will get the result.
Second, for some special security purpose, we have a very special way to identify your E3card Reader: Download the FW called Authentication.bin from the download page, copy to the E3Upgrader driver, Wait for while (typically 1~2 seconds), copy a file Auth.bin from the E3Upgrader, and then upload this file to our website, click the “Authentication” button, then you can get the result.

The second method is pretty awesome
