Dayton is a city in southwestern Ohio, and is famous for being the inventor of the plane, the Wright brothers. But in addition to the Wright brothers, there is also an inventor who is also very good. He is the inventor of the cash register, James Ritty.

In the 1870s, Ritty operated a coffee shop in Dayton. Because of his well-managed business, the coffee shop was booming, he hit the iron, expanded the store, and hired more clerk. As the business expanded, he found that he had some troubles in his own invisible.
The main reason for trouble is nothing more than a word - "money." When the shop was small, the daily flow was limited. When the door was closed at night, the profit and loss of this day was basically counted. Now the stalls are big, and they go in and out every day, which is very laborious. Also, due to the lack of effective supervision, he is not sure that every account of the cashier can be calculated accurately, and it is not certain that the cashier will be able to handle the sheep and put some business money into his own pocket.
Later, he consciously or unconsciously guarded the cashier and stared at every transaction of the cashier, so that he could rest assured. But doing this is very tired, which is equivalent to giving the cashier an assistant. Then there are a lot of things to be busy, and it is impossible to keep the checkout at all times. If there is a machine that can replace every expense of the cashier on his own, how good it is, Ritty thinks.
Of course, Ritty was not delusional. At that time, the industrial revolution had been going on for more than a hundred years, and the invention and use of machines was already very common. More importantly, Ritty also worked as an engineer before running a coffee shop, and inventing and manufacturing machines was his job. So he set out to study a machine that can supervise the cashier to collect the bank.

At first, there was no clue, until one time he traveled by boat and inadvertently saw a device on the ship that could record the number of revolutions of the propeller. The device gave him inspiration. When he went back, he drew a sketch of the design and found his brother John Ritty. The two men together created the prototype of the cash register.
The cashier designed by Ritty has a digital dial with buttons that correspond to different amounts of money. The top of the cash register has a display that can be displayed on both sides, and a digital dial is also built into it. Two digital systems are connected by internal gears. When the buttons below are pressed, the corresponding numbers appear on the display, which can be seen by both the salesperson and the customer.
Although the cash register is awkward, it already has the most important function of the modern cash register, which can record the amount of each transaction. Moreover, the customer can also see the number displayed on the cash register. If the clerk makes a mistake, the customer will definitely raise an objection, and the customer will become the supervisor of the salesperson. In this way, the boss only needs to check the money in the money bank and the records on the cash register every day. From then on, he no longer has to worry about the clerk licking the fish.

Ritty applied for a patent for the cash register in 1879 and produced some cash registers for sale to others. However, running two companies at the same time left him with some energy. Under the thought of it, he sold the patent to others and concentrated on running his own coffee shop. It seems to him that drinking coffee in a coffee shop where music is flying every day is much more pleasant than drumming a machine in a rumble factory, but he also gave up a chance to make big money.
Later, the patent owner made a major improvement to the cash register. A drawer with an automatic lock was added to the cash register. The drawer consisted of partitions of different sizes and could store different amounts of cash. A bell has also been added.
After the clerk enters the unit price and quantity, the machine automatically calculates the total number and displays it on the cash register. If the customer has no doubts, they can pay. When the customer pays, the clerk presses a button, the drawer automatically opens, and the bell rings. If the process is wrong, the cash drawer cannot be opened. Especially the bell on the cash register is a very interesting design. When the ringtone keeps ringing, it is estimated that the bosses who are relaxing in the coffee shop next door will have fun.
Of course, the cash register at this time is still mechanical, composed of various gears and digital dials. In addition to the practical functions, people also carved some decorative patterns on it, giving it a classical mechanical beauty.

With the development of electronic technology, in the 1960s, Japan took the lead in developing an electronic cash register (ECR machine), making the cash register more intelligent and more powerful. In the 1980s, the third-generation cash register (POS machine) was created, which directly changed people's payment methods.
