This elegant e-lock has three unique features. First, since your finger is the key, you never need to worry about losing it. Second, unlike most padlocks and biometric padlocks, these are distinctively designed to express your personal style. From color to shape to finish, they allow you to put your individual signature on your security. Third, the Shackle Press Pattern offers another way to unlock, allowing you to give friends access. These locks are designed for sports lovers, backpackers, students or young workers.
