Everything has gone digital: bank records, voting records, medical records, school records, social media, etc. You are out there in the world, exposed more now than ever before. Your information is literally at anyone's fingertips. This is why it is so important to be more cautious about who you share that information with and how you share it.
|Don't be this person!|
Try to keep a record of who you give information to. When you are in person, write down what companies you used your credit card at, which ones asked for your phone number or email address, and who you gave a business card to. When online, print screen, print screen, print screen. Keep a picture file on your computer (and back it up somewhere else) and dump all the print screens there. That way, if something goes wrong, you have a record of when and who has your information.
The only way to protect yourself is to protect your PII. The internet has made many things faster and more convenient, but protecting your information is not one of those things. The internet has made that harder and more tedious.
