Abstract
A method and a system for determining an amount of material remaining in a spool are provided herein. The system includes a radiofrequency identification (RFID) reader that is configured to read an RFID tag disposed at an end of a core of the spool. The RFID reader is provided on or in a vicinity of a support surface configured to hold at least a portion of the material. The system further includes a computer system in communication with the RFID reader, the computer system being configured to compute an amount of remaining material in the spool based on a thickness of the material and based on a number of revolutions of the spool. The number of revolutions is determined by a number of times the RFID tag on the spool comes in a reading vicinity of the RFID reader.
