Metal numeric keyboard is a kind of digital input equipment with metal as the main material to make keys or the overall frame, with a variety of types and characteristics, the following is a detailed introduction:
- Classification by application scenario:
Keyboard in the financial field:
ATM keyboard: The ATM of the bank usually uses a metal numeric keyboard, which is because of the high conductivity of the metal material and the rapid temperature change, which can effectively prevent the theft of passwords by means of thermal cameras. Even if someone tries to obtain the key information through the thermal sensor after the transaction, it is difficult to judge the password order according to the temperature change, which ensures the security of the user’s account. This keyboard generally has good waterproof, dustproof and wear resistance to adapt to the use of financial places such as banks.
Bank counter keyboard: The metal numeric keyboard used by bank counter staff, the keys feel comfortable, sensitive operation, can quickly and accurately input customer account information, transaction amount and other data. This type of keyboard is usually connected with the bank’s business system, which has high stability and compatibility.
Keyboards for business:
Cash register keyboard: In shopping malls, supermarkets, convenience stores and other commercial places of the cash register, metal numeric keyboard is widely used. It can quickly enter the price of goods, quantity and other information, convenient cashier settlement. For example, the cash register system of some large supermarkets is equipped with a metal numeric keyboard, the key layout is reasonable, and the numbers are clear, which can improve the efficiency of the cash register.
Logistics warehousing keyboard: In the logistics warehousing industry, the staff need to input and manage the information of the goods, and the metal numeric keyboard can be used to input the number, quantity, weight and other data of the goods. Due to the relatively complex logistics storage environment, the sturdy and durable characteristics of the metal digital keyboard can adapt to this working environment.
Industrial keyboards:
Industrial automation control keyboard: In the industrial automation production line, the metal numeric keyboard can be used for equipment parameter setting, operation instruction input, etc. For example, on some CNC machine tools and automated production equipment, the operator can input processing parameters and control instructions through the metal numeric keyboard to achieve precise control of the equipment. This type of keyboard usually has strong anti-interference ability and stability, and can work reliably in industrial environments.
Instrument and equipment control keyboard: In a variety of instruments and equipment, such as laboratory instruments, medical equipment, etc., metal numeric keyboard can be used for equipment operation and parameter adjustment. For example, the metal numeric keypad on the medical equipment can be used to input patient information, treatment parameters, etc. The metal numeric keypad on the instrument equipment needs to have high precision and high reliability to ensure the normal operation of the equipment and the accuracy of the data.
Second, according to the connection type:
Wired metal numeric keypad: connected to the device through the data line, stable data transmission, fast response speed. For example, some desktop computer supporting metal numeric keyboard, through the USB interface or PS/2 interface and computer connection, suitable for high data transmission speed and stability requirements of the scene, such as office, financial transactions.
Wireless metal digital keyboard: Using Bluetooth, Wi-Fi and other wireless technology to connect with the device, easy to use, not limited by the data line. For example, some tablet computers, smart phones and other mobile devices supporting the metal numeric keyboard, through Bluetooth connection, convenient for users to use when mobile office or entertainment.
Three, according to the key technology classification:
Mechanical axis metal numeric keyboard: the key adopts mechanical axis structure, with obvious paragraph feeling and feel feedback, the key life is long, suitable for users who have high requirements for the key feel. For example, some game players, programmers, etc., like to use a mechanical axis metal numeric keyboard, which can maintain a good feel and operating experience in long-term use.
Thin-film metal digital keyboard: The key adopts the thin-film structure, the cost is low, the key sound is small, suitable for the environment sensitive to noise. For example, the metal numeric keypads used in some offices, libraries and other places are mostly thin-film structures, which can meet the needs of digital input without causing large noise to affect others.
Capacitive metal digital keyboard: the key is input by capacitive induction principle, high sensitivity, fast response, and can achieve waterproof, dustproof and other functions. For example, some outdoor electronic equipment, such as outdoor advertising machines, self-service ticket machines, etc., are equipped with metal digital keyboards that are mostly capacitive structures and can work normally in harsh environments.
