I should have provided the context. I am using Blockstream Jade. As a part of the setting up the Jade wallet, it gives me an option to "draw" the seedQR, which is used to login to this stateless wallet (which forgets the private key when power turned off). What I don't understand is, why would anybody want to create this seedQR, which is like a card with the 12 words written on it. Sure, you can write down the words and put it away somewhere safe, but you shouldn't be using the card everytime you log in to the wallet.
Stateless wallet does not store any data locally after turning off the power. Thus, wallets are useful in case of physical attacks as If your wallet is stolen and the thief wants to brute force the wallet PIN or for those who have different seeds for a multisig wallet.
In this case, you will be required to enter the seed every time you use the wallet. To speed things up, instead of entering the words manually, you can simply scan the seedQR. If you do not need a Stateless wallet, do not use this option. the seedQR option may be bad, as everyone who accesses it accesses your money, so the option of manually writing the seed is better.
