Chase Launches New Feature to Immediately Lock Credit Cards Credit card theft is reportedly on the rise, as criminals are adapting to more sophisticated means of data scraping. Chase customers are now able to lock their credit cards immediately to prevent unauthorized activity on their account. The feature allows Chase users to freeze their credit cards from the Chase mobile app or via login at Chase.com. When misplaced cards are found, users can immediately unlock the credit cards. Locking has no effect on
automatic payments. Chase plans to implement the service for debit cards in the near future.
