NFC tags are passive devices that operate without power supply; they must fall within a certain range for activation. The tags cannot transfer data by themselves; instead, they are simply used to transfer information to an “active” device – to a Smartphone, for example.

Why did we decide on this particular method?


An NFC tag is not connected to the Internet.

And this means that it is not subject to such threats as the penetration of a trojan or other hacker attack.
2. NFC tags have a low cost.

Safe Storage of Passwords, Private Keys, and Other Important Information

The simplest NFC tag in the form of a sticker costs from 10 rubles. It is sold in almost every city.

Also, when recording, you can specify “Encrypt Data”. In this case, the program will propose you to enter a password for the data encryption. And the data will be encrypted using the AES – this is the safest data storage method.

All your sensitive data in the tag will be encrypted. And even if an attacker takes possession of your tag, he/she can only read disorganized data.

Your Answer

In order to obtain ordered data from this data chaos, the attacker will have to enter the password key for decryption, which you created when recording the tag.

As a result, we have the following: You need to create and remember only one password key. This password key will be used to encrypt and decrypt your data in the NFC tag.

This is much easier than remembering dozens of logins and passwords.

NFC tags may be in many different types and form factors as follows:

NFC stickers – these are thin stickers with a chip integrated.

Smart rings with NFC chip – all your sensitive data is in the ring on your finger in the encrypted form.

NFC implants for implantation under the skin – at the present time, the surgery for implanting an NFC chip under the skin can be performed painlessly in almost any piercing center.

The chip itself is very tiny and does not make itself felt under the skin.

NFC key chains, cards, etc.
