Techopedia Explains Point of Sale (POS)
Early electronic cash registers (ECRs) were the first POS devices with proprietary software and limited functions. In 1973, IBM announced that it had two POS devices: IBM 3650 and 3660 Store Systems, which were store controllers for 128 POS registers. This represented the first commercial use of several technologies: client/server technology, peer-to-peer communications, local area networking, simultaneous backup and remote initialization. The next year, these were installed in Pathmark and Dillard’s stores in New Jersey.
