TikTok trends encourages check fraud

(CNN)– A viral TikTok trend is encouraging people to commit what amounts to check fraud.

Videos posted to the app show people getting so called ‘free’ cash from Chase ATMs by depositing checks made out to themselves for large sums of money.

They then withdraw as much as thy can without exceeding that sum, leading them to believe they had tricked the system.

Chase says this glitch is actually a form of criminal check fraud.

It centers on a common banking practice that allows check depositors to have access to a portion of their total funds before the check actually clears.
