DefinitionA self-checkout (セルフレジ) is a register where customers themselves, rather than staff, handle everything from scanning items to paying.
ExplanationThe sales data it scans is recorded just as at a regular register, so it can be seen as one form of register running on the POS mechanism. With IC-tagged goods, it can even read a whole basket at once just by setting it down.
AnalogyLike a self-service gas station, customers do the work that staff used to handle.
Memory hookThe Japanese name pairs self with reji, short for register, so it literally reads as a self register.
