This article shows how to check the software version on your Adyen card terminal in Singapore and install an update from the terminal's Settings menu. Keeping the terminal up to date helps card payments run smoothly.
Applies to: Singapore · Adyen portable card terminal that runs Qashier POS (the QashierXS (Black), Adyen S1F2). It does not apply to other QashierXS models, the QashierX2 or the countertop Verifone V400c terminal. You need the terminal's admin password from your onboarding email.
Before you start
Charge the terminal or plug it in to power.
Connect the terminal to Wi-Fi. See [SG] How to Connect the QashierXS (Black) Portable Card Terminal to Wi-Fi.
Finish any open transaction. Do the update outside busy hours, because you cannot take card payments while it installs.
Find the terminal's admin password in your onboarding email. If you cannot find it, contact Qashier Support to verify your identity and get it.
Steps
Press the round home button at the bottom of the terminal's screen (between the triangle and square buttons) to leave Qashier POS.
Tap Settings at the bottom left of the screen.
Tap Device info.
Tap Software.
When prompted, enter the admin password.
