I got some info about keyboard as follows:
New storing device fits at the end of the keyboard cable connecting to the PC specialized to save all typed keys in it… Mostly could be used in net cafes, exhibitions, hotels and airports therefore be careful especially the people who use the internet in these places to enter their bank accounts online or any other important sites. After you enter the bank account and leave the PC it will be easy to open your account again as all what you have typed has been saved in the Black device. Therefore, you should check the PC for any suspicious piece behind it before using the net in public places for important sites. Please send it to all who you know to educate them against this fraud.
I am also attaching its picture.Whts the reality,can any one please guide?
Thanks & Kind Regards,
