Technologies and methods for security access
First Claim
1. An electronic lock, comprising:
- a dynamic display device;
an input device; and
one or more processors that are configured to;
execute a time-based cryptographic algorithm to compute a time-based access code;
cause the dynamic display device to display a machine-readable optical identifier that encodes at least a lock identifier of the electronic lock, along with at least one of;
a time received from a clock at the electronic lock,a battery level of a battery at the electronic lock,a log entry of a log at the electronic lock,a log entry count of the log at the electronic lock, ora hash of the log at the electronic lock;
based at least on displaying the machine-readable optical identifier at the dynamic display device, receive an access code at the input device;
compare the time-based access code with the received access code; and
grant access to one or more lock features when the time-based access code matches the received access code.

Abstract
Embodiments herein are directed security access. Embodiments include an electronic lock that executes a time-based cryptographic algorithm to compute a time-based access code. The electronic lock compares the time-based access code with a received access code, and grants access to one or more lock features when the time-based access code matches the received access code. Embodiments also include providing an unlock code, including receiving a lock identifier and a user identifier. The lock identifier and the user identifier are sent to a remote computer system, and an access code for the lock is received from the remote computer system. Embodiments also include an electronic lock that receives and verifies an access code that includes a validity start time and a validity end time. When the current time is within the validity start time and the validity end time, the electronic lock grants access to one or more lock features.
