Avoid credit card fraud during travel
Set up alerts
Norville also recommends taking advantage of whatever kinds of alerts you can receive while you're away. If you'll be able to receive text messages at your destination, explore what kinds of options your issuers offer as far as text alerts.
Many will let you set an alert that will send you a text message if a purchase over a certain dollar amount is made, for instance. Not a texter? You might want to get your alerts via email if you'll bring your laptop or smartphone.
Norville says these alerts can even help you stick to your budget, if you set an alert that will contact you if your balance goes above a certain threshold. When you get home, you can disconnect those alerts as easily as you set them up.
