Fingerprint configuration

Mercado Pago has its own fraud prevention tools. Device Fingerprint is an identifier that acts in the processing of a payment, with the aim of improving the fraud risk analysis in each transaction.

Whenever possible, we recommend that you submit information on customer behavior to detect unusual movements and avoid fraudulent transactions. Don't worry, we take care of your customers' data and we don't share it with anyone.

To configure Device Fingerprint, follow the steps below:

  1. In your store's administration panel, access **Checkout > Store Setup.
  2. Click on the edit icon to access the configuration of your site.
  3. In the Files module, access the Code tab and click on checkout6-custom.js.
  4. Copy and paste the following code, then click on Save.


var script = document.createElement("script");
script.src = "";
