Hide Your PIN or Password On a Fake Business Card With Magic Ink

This DIY fake business card will only reveal your secret note when you give it a little heat.

Then create and print out an extra logo that matches the card (with your note printed inside).

Then cut out the newly painted logo and attach it to your business card with some glue.

And if your wallet or purse gets stolen, thieves will never be able to find it.
