Dr. Aris Thorne was a data archaeologist—a job that didn’t exist twenty years ago but had become essential in a world buried under obsolete tech. His current contract: recover the original specifications for the , a biometric access control module from the 2040s. The problem? Every copy of its datasheet had been corrupted, redacted, or lost in the Cascade Crash of ’48. This is a consumer-grade security device that uses

For the module to work effectively, you must attach an antenna.
I searched for a specific "YL-105" datasheet, but it is (like for a major IC, transistor, or sensor). This code is most likely used in one of two contexts:
