Revolut has temporarily halted a refugee-related referral program after some consumers gamed the program. The London-based fintech had offered bonuses of up to about $70 for customers who referred up to five refugees from Ukraine for a fee-free payment accounts for the refugees. Revolut reports the program has onboarded tens of thousands of users in less than six weeks, but its controls found a "small number" of accounts were targeted by people who were trying to exploit the program, reports CityAm in London. Revolut's Russian-born founder, Nik Storonsky, a citizen of the U.K., in March condemned Russia's Ukraine invasion before launching the referral service. —John Adams

Rabobank has launched Carbon Insights, a feature that allows consumers to track CO2 emissions for each euro they spend through the bank's mobile app. The Dutch bank has deployed Carbon Insights with 1,000 consumers and plans to make it available to all of its 8 million private customers by September. The app divides spending into categories such as groceries, transportation, clothing and travel. Consumers can also add context to transactions, such as if they eat meat or own a car. The bank hopes this context will provide information that consumers can use to guide purchasing decisions. —John Adams
