jeff |
using a barcode scanner to transmit unexpected/unanticipated keystrokes to a host system, especially things like control characters and commands/scripts instead of just data. |

jeff |
actually, i think i demonstrated or described it to you at the first evergreen conf. |

had a lot of fun trial-and-erroring some theories on barcode scanners prior to that, demonstrated to co-workers, got the "i'm glad you're on OUR side" compliment from one. :-) |

you can reliably crash most self check machines doing that |

there's hours of fun to be had with some writable nfc stickers and a phone |

rangi |
most will crash with the equiv of a buffer overflow if you present the self check machine with an nfc card that has a massively long barcode |

most fragile 10k+ machine you'll ever meet |
