Which type of lock requires entering a code to gain access?

1. Magnetic stripe card lock

2. Proximity card lock

3. Biometric lock

4. Cipher lock

The correct answer is: Cipher lock

A cipher lock is a type of locking mechanism that requires the user to input a specific code to unlock it. This code is typically entered through a keypad, which may consist of numeric buttons or a combination of alphanumeric characters. Cipher locks are commonly used for securing doors in various settings, such as offices and restricted areas, where access control is essential. The use of a code provides a straightforward means of ensuring that only authorized individuals can enter a particular area. The implementation of changing codes also enhances security, as it allows for the frequent updating of access credentials without the need to replace physical keys or cards. In contrast, magnetic stripe card locks, proximity card locks, and biometric locks utilize different methods for access control. Magnetic stripe and proximity card locks rely on physical cards, while biometric locks require a unique biological characteristic, such as a fingerprint or iris scan, for granting access. These mechanisms do not utilize a code entry system like a cipher lock does.
