That is normally a temporary/test charge to determine if you have a valid credit card/bank card account. Did you recently sign up for a subscription? If so, that charge should disappear, and the subscription charge will occur.
If you didn't sign up for a subscription, then it is also possible that someone has hacked your account and is testing to see if they can use your card. If that is the case, I would contact your bank/credit card company.
