To check if your Ingenico terminal is charging, look for the charging indicator on the device’s screen or LED lights. Most Ingenico terminals have a battery icon that will show a charging symbol when plugged in and charging. Additionally, some models display a percentage of battery charge. If your terminal has an LED light near the charging port, it may change color to indicate charging status (e.g., red while charging, green when fully charged). If you are still unsure, refer to your terminal’s user manual for specific charging indicators, or check with your payment processor for troubleshooting.
