For the safety and protection of our customer’s (and your customer’s information), we have to lay down some ground rules.


1.) No authentication of products that did not originate from you.

If you bought a luxury clothing item that didn’t have an NFC authentication tag in it, you cannot act as a third-party guarantor of authenticity.

2.) No storing of personal information within a tag’s metadata.

This does not include unique IDs that point to a user’s information in a system outside of ETRNL.

3.) These tags should not be used to gain access to any highly sensitive information such as medical records, legal documents, or personal information

If you’re not sure if your use case is acceptable, please chat with us in our Discord Channel. We’re happy to answer any questions and make sure your customers get the best experience.
