Description

Self-Service Bill-to-Bill and Coin Change Machine

KER Self-Service Cash Change Machine is an automated currency exchange terminal designed to convert large-denomination banknotes into smaller bills and coins.

Customers simply insert an accepted banknote, and the machine verifies the note before dispensing the configured combination of smaller banknotes, coins or both. The entire exchange process can be completed independently without assistance from staff.

This solution is suitable for businesses and public locations where customers frequently require change, helping operators reduce manual cash exchange, improve service availability and lower cashier workload.

The machine can be customized for different currencies, denominations, dispensing combinations and application environments.
