The USB interface (Universal Serial Bus) may be one of the most familiar interfaces. It is widely used in information and communication products such as personal computers and mobile devices. For smart touch products, the USB interface is almost indispensable for every machine. Whether it is a printer, scanner, or various other peripherals, they can be connected to the POS terminal or All-in-one machine quickly and easily via the USB interface.

There are various types of USB interfaces on the market, and the most common USB 2.0 or USB 3.0 can often be seen at the interface connection of smart touch products. Both USB 2.0 and USB 3.0 were built on the first USB technologies, USB 1.0 and 1.1, which were released in 1996 and 1998, respectively. There is no doubt that USB 1.0 is the most basic of all types, with a maximum speed of 1.5Mbps per second. So what is the difference between USB 2.0 and USB 3.0?

First of all, in terms of appearance, the inside color of the USB 2.0 connector is white or black, while the inside of the USB 3.0 connector is blue, which is also easy to distinguish. In addition, USB 2.0 has a total of 4 connector lines, and USB 3.0 has a total of 9 connector lines.

In terms of performance, USB 2.0 transfer speed is relatively slow, about 480Mbps. The speed of USB 3.0 has been greatly improved, 10 times faster than the former, and the transmission speed is about 5Gbps. Its ultra-fast transmission speed is especially useful when backing up data or transferring large amounts of data, especially for supermarket chains using modern cashier POS machines, managers will be more inclined to use efficient solutions.

Above that, USB 2.0 consumes 500 mA while USB 3.0 draws up to 900 mA. USB 3.0 devices provide more power when in use, but conserve power when idle.

Generally speaking, USB 3.0 provides faster speed and more efficient data management than USB 2.0, and the 3.0 series has Backward Compatibility, and products adapted to 2.0 can also be used normally under the connection of the 3.0 interface. However, USB 3.0 has a more expensive price, so you can consider the above information when choosing whether you need an upgraded version of the USB type.

Different USB interface types can provide a very different user experience. In addition to USB 2.0 and USB 3.0, there are Type-B, Mini USB, Micro USB, etc., all of which have their own compatibility restrictions.
