<prompt> Human: I have a Citibank Double Cash card that I use for literally everything except gas and groceries because my AMEX gets 3 and 6 CB for these categories. I pay it off every month and save the 2. CB rewards. Ive had it for around 9 months now and have over 700 CB saved up so far.Anyway, I got up around 1am to go to the bathroom and while up checked the time on my phone. To my surprise there were 2 notifications that my card was recently used at a gas station and McDonalds 19.50 and 19.24 literally 15 and 5 minutes prior to me looking at it at Bronx, NY. Ive never been there before BTW.I went right into the app and was able to shutdown my card instantly via the app. Ill call then first thing in the morning to open a case, but it really gives me peace of mind that for the rest of the night it wont be used any further. I REALLY like that feature and wish all CCs offered that feature. I looked and my AMEX Blue Cash Preferred doesnt. Im not sure why, seems like it would only benefit the CC company to do so since they usually eat the costs of fraud charges anyway. Im also a fan of the instant notifications which alerted me of the problem nearly instantly both have this feature though.So anyway, hoping it works out tomorrow to get reimbursed but wanted to share what happened. If youre looking for a new card this feature with the Citi Double Cash plus awesome CB is something to consider.  <response>: Discover also has the option to freeze your cards too. Not all companies do this unfortunately.
