I have notification of any cc purchases texted to my I phone.
I also have receive a few Text messages that I was purchasing items, in some states a long way away. and I call my credit card company right away. The last time, I was on the phone with a credit card rep while someone was trying to purchase some items in different states at the same time.
with my credit cards I have my cell phone set up to receive text messages fro all purchase's and the cc company will call if they spot anything unusual happening.
plus they know that I call them when I am making an un usual purchase. letting them know the business and approximate amount of the purchase.
