Frequently Asked Questions

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.

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.

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 or more 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 or more 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 remember to change the cards at the end of 5 years.

You can buy NFCVault package to take advantage of this technology that allows you to be free of any worries about keeping your private keys. We have 3 NFC Vault packages (Standard, Premium and Platinum). When you buying Premium or Platinum package, we offer the shipping costs.

The process of recording the private key on the NFC card is an offline process, so no one can access that information. That's what makes this process safe. Each user is responsible for keeping their cards safe. The greater the number of NFC cards, the greater the security, as long as they are stored in different places. The custody of the cards and private keys is the sole responsibility of the customer.

NFCVault.io app requires the Airplane mode to be enabled because it helps to ensure the security of the seed phrases that are being stored on the NFC tags. When Airplane mode is enabled, it disables all wireless connections on the mobile device, including Wi-Fi, Bluetooth, and cellular data.

By disabling all wireless connections, NFCVault.io can prevent any potential interception or tampering with the seed phrases during the backup and recovery process. This is because NFCVault.io uses the Near Field Communication (NFC) technology to read and write to the NFC tags, which requires close proximity between the mobile device and the NFC tag.

Enabling Airplane mode also helps to reduce the risk of any potential interference during the backup and recovery process. Overall, requiring the Airplane mode to be enabled during the backup and recovery process is a security measure designed to protect the seed phrases and ensure their safe and reliable storage.
