Encryption display card

摘要

There is provided an easy-to-carry encryption display card which can generate and store a random encryption and display the encryption when the user wishes to check the encryption. The encryption display card has a main body of a thin plate and includes: a control circuit 2 for switching between two modes including an encryption registration mode and an encryption search mode; input keys 7 for accepting an input of label data; an encryption generating unit 22 for, upon input of the label data in the encryption registration mode, generating a random encryption for a label equivalent to the label data; a RAM 3 for storing the encryption in a one-to-one correspondence with the label; and a display panel 6 for, upon input of the label data in the encryption search mode, displaying the encryption for the label equivalent to the label data. A random encryption is generated by merely inputting the label data when registering an encryption, and the target encryption is displayed by merely inputting the label data when searching the encryption. <IMAGE>
