Another hardware that lodges the pattern of keystrokes is called the Data sniffers. This device picks up signals of wireless data which can be used to log keystrokes on wireless keyboards. To gain access to the information they need, hardware key loggers need to be connected to a computer device but some of these devices can transmit wirelessly.
