The Story of Postcards

Every postcard is a miniature world, with scenery, art design, or a simple blessing carefully selected by the sender, carrying the emotions and feelings of that time and place. In 1949, the first set of Chinese postal postcards was issued by the People's Republic of China. In the 1980s and 1990s, postcards became the main means of holiday greetings for young people.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

A postcard is a type of card used for writing text, containing images, and can be sent to a post office without the need for a letter. It is typically used to send short messages through the postal system. Not only is it convenient for people to share information and emotions, but it is also a form of cultural exchange and artistic display. The world's first postcard was introduced in Austria in October 1869, and subsequently other countries began to use it as well. The front of a postcard is in the format of an envelope, while the back has the function of a letter. The advantage is that it does not require an envelope, but the disadvantage is that it is small in length and has no confidentiality. The content written on it is public, so it is called a postcard.
