Development of the SD memory card with the lock function of reading data

Abstract

We are using standard Digital Video Camera/Camcorders with SD memory card for our work. But there was anxiety of loss and theft for a SD memory card including personal information. We developed SD memory card has a mechanism to protect the stored data enabled by the NFC (Near Field Communication) technology. This SD memory card interface can be locked not to read the data but could still continuously write the data.
