Abstract
A print consumable may include a rotatable core, a roll of dispensable print substrate, and a radio-frequency identification (RFID) tag. The roll of the dispensable print substrate may be dispensably secured to the core. The RFID tag may be secured to the core and configured to rotate about a core axis. The RFID tag includes an RFID antenna coupled to an RFID chip. The RFID chip may include a print counter, a stock-keeping unit (SKU) code, and a consumable authentication code. A print system may include a housing, a holder to hold the print consumable, a print head, a transceiver, a trace antenna for reading an RFID tag of the print consumable, and a controller. The controller may be configured to receive a signal from the transceiver indicative of one or more of the print counter, the SKU code, and the consumable authentication code received from the RFID antenna.
