The keyboard is a necessary part of a computer. As an input device, we can only type in what we need through the keyboard. However, if it's ready-made files or images, they cannot be entered into the computer via the keyboard, and another input device, a scanner, is required. But now, all these functions can be realized through this kind of keyboard. Because this is a scanner keyboard, in addition to being a keyboard, it also adds the function of a scanner. It takes only 5 seconds to scan A4-sized documents, and about 14-15 seconds for general color documents, so the speed is relatively fast. Moreover, cards with a thickness of less than 1mm can also be scanned, such as ID cards, membership cards, etc. However, the current selling price is not low, at $140.
