MasterCard's Selfie Passwords: 10 To AvoidMasterCard's Selfie Passwords: 10 To Avoid

Millennials: Why Customer Service Will Never Be The Same

MasterCard is trying to make online purchases more secure, and it's decided the best way to do that is take advantage of society's current favorite narcissistic pastime, the selfie. The credit card company hopes that the process can replace codes that can be forgotten or stolen, and that your beautiful face cannot be copied so easily.

MasterCard said it's testing the system with 500 users. The process is fairly simple. You put a picture on file with MasterCard. When you make a purchase using a smartphone, MasterCard will ask you to take another selfie. You pose and give your best smile for the camera, and then send it to MasterCard, which uses facial recognition technology to compare it to the picture on file to see if you are really you.

I'd worry about facial recognition a bit, since Google's tagging system appears to have some big problems. But hey, if they can work the kinks out, the plan seems reasonable enough.

Still, there's a major issue. What picture do you use on file? That great one of you at the beach? The one when you flashed the perfect duck face for the camera? That candid shot of you at Disneyland? Tough decisions. I mean, this picture will be your identity forever. When you buy something, some computer is going to see it. AI is getting better every day. Some AI will be judging you.

With that in mind, we decided some advice was worthwhile on a few types of pictures to avoid. We present to you:

10 (Clean) Selfies To Never Use As A Password

1. Even if you are in space, a helmet is bad idea. By the way, if you think you are all cool with your selfies, remember Buzz Aldrin took this in 1966.

2. Religious figures will probably not work. Their halos will ruin the lighting.

3. Unless you make all your purchases under the water, or you credit card is with the Outer Banks, avoid underwater selfies.

4. Don't get artsy.

6. You can take the duck face trend too far. (Note: I'm not making fun of anyone. This was done with a photo effect.)

7. Think about your hair. Keep it out of your face for more accurate recognition.

8. Don't forget to look right at the camera.

9. When in doubt, have someone take the picture for you. But we wouldn't recommend an elephant.

10. Facial hair might be a problem. But always dress formally. With at least 10 ties.
