[0001]
BACKGROUND OF THE INVENTION
In the present invention, the postcard body piece and the postcard sticking piece are connected via a sewing line, and the postcard body piece and the postcard sticking piece are folded from the sewing line and bonded in a peelable manner. Concerning cover postcards.
[0002]
[Prior art]
Conventionally, a postcard body piece and a postcard sticking piece are connected via a sewing line, and the postcard body piece and the postcard sticking piece are folded from the sewing line and bonded in a peelable manner. Postcards are already known and are used to notify confidential information to a third party. (For example, see Patent Document 1)
[0003]
For example, when e-mail communication is performed via the Internet using a personal computer or mobile phone, it is possible to prevent a third party from seeing the e-mail without permission by setting secret information such as a personal identification number to prove the identity of the person. However, when these e-mails are sent for the first time, the communication management company may notify the user to confirm the password.
However, when a family member applies for a personal identification number for each family member and informs them of this, if a single information concealment postcard is used, the personal family member's personal identification number will be known to other family members. There is a problem that privacy is not protected.
[0004]
In addition, if a personal identification number is sent to each family member using an information concealment postcard, the costs of postcards and postage will increase, making it difficult for the communication management company to pay for the costs and processing. There's a problem.
