If you've uncovered some payment card details online you can report them here so that the card issuers can act to prevent payment fraud occuring and impacting the cardholders.

Just submit a plain text file (e.g. .txt) containing the card details. No specific format for the file is required (we aim to make it as painless as possible for you). We parse out the card numbers line by line.

This platform is designed to be secure, it salts, hashes, encrypts and then hashes (again) the card numbers. It never stores plaintext versions of the card details you submit. We also never store the file you upload, it's read and then the contents are sent for processing - the data never touches disk on our systems in an unencrypted format.

Once you have uploaded your file we do some preliminary parsing to give you some stats on what we found in the file you shared before it is subject to our processing queue. We don't currently have functionality to provide you full details once the file has been processed, but we're working on it.
