Abstract
A wireless IC memory, for improving the security thereof, for achieving protection of business information and privacy, comprises an RFID tag, wherein it is possible to setup 'readout disenabling (ReadLock)' condition to the UII code bank for storing ID data of the RFID tag, with a predetermined protocol from an external communication apparatus, within the RFID tag. Setup of 'readout disenabling (ReadLock)' condition is stored on a readout enabling/disenabling condition memory portionwithin the RFID tag. In case where the “readout disenabling (ReadLock)” condition is set up in the UII code bank, a protocol process controller portionof the RFID tag, not responding the UII code, normally, but answers a fake UII code or an error code, or gives no answer, to a request or command of readout of the UII data from the external communication apparatus.
