ETRNL VAULT is a high security platform that makes NFC authentication easy and affordable.

With ETRNL, you get **FULL control** of:

* Your customers' data
* Your users' experiences
* The design & placement of the physical tags in your product

And after your tag is programmed, we'll make sure that its encryption keys are protected for the lifespan of the tag.

Our Programmer in combination with our [API](/api-reference/endpoints/tags/verify-authenticity) gives you an easy way to personalize and program a massive number of tags quickly while
also keeping your customer's data in-house.
No need to spend countless hours reading through complex documentation because now you can get up and running in minutes.
