Abstract
A readable and writable radio frequency identification (RFID) tag is attached to a physical medium such as a CDROM or DVD. Each time a copy of the medium is created, a variable or count stored in the writable RFID is updated. In cases where the mechanism for reading and writing the RFID is in communication with the device making a copy of the medium, the created copy can have its permitted number of copies set to zero, or other restrictions put in place. Or the device can be prevented from making any copies. In this manner the total number of copies of an original product can be regulated. The RFID can be read or written from a mechanism in a CDROM or DVD player or the read/write mechanism can be in a different device such as in a computer, or in another device.
