Abstract:
A consumable can be used to securely send data to devices. A security platform can produce a consumable, for example an ink cartridge, with data to be uploaded onto a device, such as a printer. If the consumable and device can perform a successful authentication, broadcast data can be delivered to the device via the consumable. Such techniques can help ensure that authentic consumables are being used in authentic devise. Further, such techniques can enable a licensing model where different consumables can be configured with different data to enable or disable different features of the device.
