Suggest you go with your camino plans, and not be too concerned about your data. I would be proactive about monitoring your credit reports periodically. And I always ask my CC companys for new cards after using the on an international trip. I tend to stay at hotels or private places and they take most of this data anyway.
I've never asked my Bank for 'new' cards, but I tend to take 2-3 just in case of problems.
I have to say the fraud protection by the banks we use here in Australia is really good in our experience at least.
I even had a call that went..........
Bank.
Are you in Manila?
Me.
No.
Bank.
So you didn't just buy a diamond ring valued at $5.000?
Me.
No!
Bank.
Don't worry, we didn't approve the transaction, as it was did not fit your normal spending profile.
I now also tell my bank of my travel plans. with dates and countries.
One lesson I learned last year though.
How do you contact your bank when overseas?
And how do you 'approve' payments that they might hold until you confirm they are legit.
I had my phone set to SMS messaging for such things.
Of course with a Spanish SIM card this didn't work.
(though I had my home SIM with me, just not in the phone)
So on calling the bank, they switched the approval process for me.
I can now do it through the phone app.
