DigiSaveBox use only visible QR codes to communicate to the outside world and can be verified at all times. You can also use our patent pending oneway dongle to transfer your data and stay in control. No direct connection to the outside world. No USB, No Wifi, No Bluthooth, nothing! You simply cant hack remotely to an offline device that has not connection to the outside world. Even we cant access your files. DigiSafeGuard is for anyone that wants real security and privacy and not just a gimmick giving you a false secure feeling. Any other device connected to the outside world by usb, wifi, bluetooth etc… is simply not secure! They are maybe easier in use, but not secure! Just because the protocol has been designed to function in a perfect world and not grant access to a hacker doesn’t mean they cant get in. Hackers find always a workaround and flaws to bypass protocols. You should ask your self if your willing to trust any software or protocol to keep the hackers out, or just cut the remote connections and be sure of your security!!!
