Due to the development of the technology and financial payment industry, ordinary conventional keyboards have not been well adapted to the flexible applications in their application fields, so there is a keyboard that can independently program each key-programmable keyboard. The difference between a programmable keyboard and a regular keyboard: 1 Number of keys. In addition to the 101 and 104 keys of the programmable keyboard, there are 60 keys, 78 keys and so on. . It should be said that there is no standard. The number of keyboards can be determined according to the needs of the developer. 2 The arrangement of keyboards. The alphabetical arrangement of the programmable keyboard does not have a relatively fixed pattern like the conventional keyboard, which can reflect more personalization and professionalism. 3 Button definition. The programmable keyboard can redefine each key multiple times. Can be defined as text, letters or a command. Each keyboard comes with a corresponding programming program, which is easy to learn.
