If you have used personal computers in the past, you may have come across the PS/2 mouse. It is a device that was first introduced by IBM in 1987, alongside the Personal System/2 desktop computers. Its name is derived from the computer series it was launched with.
The PS/2 mouse connector replaced the older DE-9 RS-232 “serial mouse” connector, while the PS/2 keyboard connector replaced the larger 5-pin/180° DIN connector used in the IBM PC/AT design. This improvement allowed for faster and more efficient communication between the computer and mouse.
New Innovations in Payment Systems
The rise of smartphones has brought with it many innovations, including new payment systems. While many web-based payment systems were created in the 1990s, only a few, such as PayPal, have managed to survive till date.
Smartphones have the added benefit that users can use them while shopping, and their integrated fingerprint readers significantly increase their security. Near Field Communication (NFC) is the leading technology used in mobile payments. It enables users to pay for goods instantly by passing their phone over a terminal. Many Android phones already had NFC, while Apple integrated it officially into the iPhone 6.
In addition to NFC, barcodes and QR codes are also employed. They are shown on phones and scanned by a terminal at the store, leading to quick and easy payments.
