MasterCard customers may soon be able to make their online purchases more secure by verifying their identity with a selfie.

The company will soon start testing a new technology that will allow shoppers to use fingerprints and facial scans to prevent fraudulent purchases, according to CNN Money. The trial will begin with 500 customers, who must use the MasterCard app on their phone, either presenting their finger prints or posing for the camera when prompted.

To prevent fraudsters from simply using a photo of the real cardholder, users will be asked to blink to demonstrate that they are really there, not simply a static image. The resulting photo will be converted to code and compared to an algorithm on file.

If the trial run goes well, MasterCard hopes to take the technology to a wider pool of customers.

There are some things money can’t buy. For everything else, there’s selfies.
