The ATMs will display information on two types of urgent messages: Amber alerts, when a child has been reported missing and is in immediate danger, and Vermist Kind alerts, which are issued when authorities are worried about the wellbeing of a missing child. In both cases, the machines will display photos of the missing kids along with relevant information about the child that may help to discover their whereabouts. When there isn't an alert to display, the ATMs will run a secondary campaign that urges Dutch citizens to sign up to receive Amber alerts on their phones.
Amber alerts have been around since the 1990s and have been expanding as technology has evolved. In 2016, the US Federal Communications Commission approved an expansion of the Wireless Emergency Alerts system that allows urgent messages including Amber alerts to be delivered directly to cell phones. Even tech companies have taken to integrate the warnings into their services, with Waze and Google both adding Amber alerts to their platforms.
