Coding machine is a non-contact inkjet marking system controlled by single chip microcomputer. By controlling the internal gear pump or supplying compressed gas from the outside of the machine, a certain pressure is applied to the ink in the system, so that the ink is ejected through a nozzle with an aperture of several tens of microns and hit at different positions on the surface of the product respectively, so as to form various required characters, patterns or logos. However, coding machine products belong to mechanical products, and it is generally necessary to apply for CE certification if they want to export into the EU market.

Game machines generally refer to electronic game machines, which are divided into three basic types: home host, arcade and handheld. Its main hardware components include CPU, memory, storage media, audio-visual output equipment, signal input equipment, etc. Generally, it is necessary to handle quality inspection reports if such products want to be put on the domestic e-commerce platform.

Bluetooth remote controller refers to an electronic product that uses Bluetooth wireless transmission technology to control remote devices. It can not only receive, but also \"transmit\", allowing electronic devices equipped with Bluetooth to communicate with each other. However, in general, this kind of intelligent electronic products need to apply for FCC-ID certification in the United States if they want to export into the American market.

Electric scissors is a kind of double insulated hand-held electric tool, which can cut various shapes of steel plates conveniently and quickly, and has the characteristics of light weight, safety and reliability. It is widely used in sheet metal occasions in automobile, shipbuilding, aircraft and repair departments to cut thin plates, metal plates and other plates. However, if such products want to enter the EU market, they need to apply for CE certification.

Intelligent sweeper, also known as automatic sweeper, intelligent vacuum cleaner, sweeping robot, etc., is one of the intelligent household appliances. The intelligent sweeper is small in size, can freely enter any corner of the home, and is cleaned regularly, which is both worry-free and labor-saving. However, intelligent sweepers need CCC certification if they want to sell in the domestic market.

Sensors are generally composed of four parts: sensitive components, conversion components, conversion circuits, and auxiliary power supplies. In the information age of today\'s society, sensors have played an important role in various fields, as they are an important means of obtaining information in the fields of nature and production. According to their purpose, sensors can usually be divided into pressure sensors, position sensors, energy consumption sensors, thermal sensors, etc. But if sensors want to be sold in the EU market, they need to apply for CE certification and attach CE labels.

The remote control car is a model car that can be remotely controlled by a 2.4GHz radio remote controller. Generally can be divided into: toys, car models (R/C), police and so on. According to the appearance of the car body, it can be divided into: RV (flat sports car), off-road car, cart, pull cart, container truck and so on. Remote-controlled cars have many scientific uses, including dangerous environment, working in deep sea and space exploration. But in general, this kind of wireless products need SRRC certification if they want to be put on the domestic market.

Energy storage power refers to the storage of electric energy, and the usual mobile phone charging treasure can also be regarded as a kind of energy storage power, but generally the energy storage power refers to the power supply with high battery capacity and high charging and discharging current. Energy storage power supply has the characteristics of light weight, large capacity, high power, long service life and strong stability. It can output common power interfaces such as DC and AC, and can also supply power for notebook computers, drones, photographic lights, projectors, rice cookers, electric fans, kettles and other equipment. However, in general, such products need to be certified by FCC if they want to export into the American market.
