A software enthusiast from Denmark created a cardboard box that requires three types of authentication before opening.
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.
When all three methods of authentication have been provided the cardboard box opens and reveals half a banana.
The filmer explained: "I scanned my credit card, punched in a six-digit code and then, at last, I used facial recognition.
"Only this will grant me access to the half banana."
