A software enthusiast from Denmark created a cardboard box that requires three types of authentication before opening.<br /><br />The humourous footage captured on May 21 shows a bank card being used on a contactless scanner followed by a six-digit code and finally a facial recognition test.<br /><br />When all three methods of authentication have been provided the cardboard box opens and reveals half a banana.<br /><br />The filmer explained: "I scanned my credit card, punched in a six-digit code and then, at last, I used facial recognition. <br /><br />"Only this will grant me access to the half banana."
