The COLOP e-mark app works in combination with the COLOP e-marking device. For operating the e-mark with your smartphone or tablet, download the free app and make customized imprints immediately from anywhere! The app is available for Android and iOS devices in the Google Play Store or AppStore. Please follow the installation guide in the App, which includes connecting to the e-mark device via a WiFi connection. You will need the SSID and password for setup which can be located on the Quick Setup Guide and is saved as an imprint in the e-mark when you initially receive it.
