To set up your BBPOS WisePOS reader, start by unboxing the device and ensuring all components are included. Power it on by holding the power button until the screen lights up. Follow the on-screen prompts to connect to a stable Wi-Fi network, which is necessary for processing transactions. Check for any software updates and install them if required. Once the device is ready, note the device code displayed on the screen, as you will need it to connect to the On The Stage dashboard. Finally, ensure the reader is fully charged or plugged in to avoid interruptions during use.
