- Reader SDK may not be used for unattended terminals. Using Reader SDK to implement payment solutions in unattended terminals or kiosks (for example, vending machines) is strictly prohibited.
1 - What is the reason for this?
2 - What defines an unattended terminal/kiosk? Does this include self service kiosks that reside within a place of business that contains employees?
Unfortunately, our hardware and software are not suitable for an unattended payment scenario, such as a vending machine or unattended kiosk.
Please make sure that your payment terminal is only available during business hours and is within line-of-sight of employees at all times.
