# 23.	What is the Matrix Bio-Wallet?

Bio-wallets are devices that use biometric information as identifiers. The Matrix BioWallet is a hardware wallet that revolves around finger vein recognition. It supports the unlocking of your wallet as well as the signing of transactions using one’s finger vein, thus saving people from the stress of having to remember a password/PIN, and more. In theory, you would never lose access to the Bio-Wallet by forgetting your password.
