JP-A-2002-183693

However, in such a business card with a barcode, the barcode is displayed on the exposed surface of the business card (card), and if a photograph is taken with a camera, copying is easy and there is a problem in security. In addition, since the URL of the information displayed on the smartphone can be copied, it is also a security problem that the information can be spread without using a camera. In addition, the barcode could not be read by the camera in dark places. Furthermore, it was necessary to secure a space for displaying the barcode on the exposed surface of the limited business card (card).

Therefore, as a result of diligent research, the inventor found that if an NFC tag was adopted instead of the barcode, all the above-mentioned problems would be solved, and the NFC-tagged business card of the present invention was completed.

The present invention has been made in view of such a conventional technique, has higher security than the case of a bar code, can read the address of the content provider even in a dark place, and uses an NFC tag as a card. When buried, it is an object of the present invention to provide a business card with an NFC tag that can use the entire exposed surface of the business card as a display area for the contents of the business card.

The present invention according to claim 1 is provided with a card in which the contents of a business card are displayed on an exposed surface and a part of the exposed surface of the card or inside the card, and stores the address of a destination for providing a predetermined content. It is a business card with an NFC tag characterized by having an NFC tag having a tag storage unit.

The material of the card is arbitrary. For example, various types of paper, various types of plastic, and the like can be adopted.
The shape of the card is generally rectangular but arbitrary.
The size of the card is arbitrary. For example, in the case of a rectangular card, the length is generally 91 mm and the width is 55 mm, but it may be larger or smaller.
The exposed surfaces of the card are the front and back surfaces of the card.
The content of the business card is arbitrary. For example, the person's name, affiliation, contact information, etc. can be mentioned.

The type of content is not limited. For example, images (including moving images and still images), character strings (including messages, etc.), sounds (including music), and the like can be mentioned. Specifically, in the case of business cards for restaurants and customer service, limited messages for retaining regular customers, attracting customers at restaurants, and other contents can be delivered. In the case of business cards of entertainers and celebrities, limited content of idols, talents, and artists (including electronic tickets for live admission) can be distributed. Furthermore, in the case of general business people, videos of seminars, general meetings of shareholders, company information sessions, etc. can be distributed in a limited manner. Furthermore, in the case of business cards for family and acquaintances, they can be delivered as gifts for special occasions such as birthdays and weddings.

In the case of business cards for shrines and temples, for example, the above-mentioned contents can be distributed such as a talisman for passing prayers and a "red stamp" that can be received as a proof of worship.
In other words, the boom of Goshuin is still continuing, and there was a line at the Goshuin awarding office to receive it, and the social distance to prevent the spread of the new coronavirus (COVID-19) could not be observed.
Therefore, for example, by simply visiting a shrine or temple and receiving a business card with an NFC tag from a shrine priest or a priest of a temple, the red stamp can be distributed (mailed if desired).

The NFC (Near Field Communication) tag is an RFID (Radio frequency identification) for performing short-range wireless communication of about 10 cm.
