## What is NFC Vault?

Currently, there are not safe ways to store the seed phrases of your wallets on the market, with the exception of writing on paper or other material (wood, iron, etc.), since keeping the seed phrases online is like leaving the key on the door of your house. What we propose is to create an innovative system that combines technology with the security of having your keywords saved offline.

How It works?
We provide a card with NFC technology (Near Field Communication) and a mobile app that can read and write the chip on the card. NFC technology is a set of short-range wireless technologies, typically requiring a distance of 4cm or less to initiate a connection. We have developed an app that allows you to encrypt your account with your NFC card, thus allowing you to read and write on the card's chip in a totally secure way, since both the writing and the reading of the chip are done with the mobile phone offline (the mobile data being turned off before entering the chip reading and writing mode). Your seed phrases are stored on an NFC chip, impossible to read by anyone who accesses it, since you need to sign in the account that has the access information to read the encrypted chip. Each user can only read their cards and each card can only be read by the user who encrypted it.

Why it’s the best way to secure your crypto assets?
Everyone knows that not your keys, not your coins. So, the goal to security is keeping the seed phrases hidden and easy to use, if needed. With NFC Vault we achieve this:

- Anyone accessing the card cannot read the keywords, unlike a piece of paper or metal.

- It is water resistant because the chip is inside the card, unlike paper.

- The combination of 2 cards is the most secure way, loss or misplacement of a card would not cause the loss of the keywords, since you always have another 1 card to read and save the information.

- Allows you to give the second to family or friend to keep them, with the security that they cannot read what is written on the chip, unlike what would happen with a piece of paper or metal. - The durability of the chip, according to the studies of the producers, is 8 years, but as we do not want to take unnecessary risks, we will exchange the cards at the end of 5 years.

## Frequently asked questions about NFC Vault
