PayPal is most popular for online payments processor and arguably pioneered the 21st-century online payment processing market. It began with a simple electronic payments system in the 1990s and has since expanded into many other services, including a point of sale (POS) system.
In 2012, PayPal launched a POS solution called PayPal Here. Then, in 2018, it acquired a Swedish company, iZettle, that offered a POS solution, among other services. In 2021, PayPal Here was retired and replaced by the PayPal Zettle POS. This service lets businesses accept in-person payments and keep extensive financial records.
