> I ofc don’t know what I dont know, but super curious if anyone has insight into why such a complex system is required
Because it's much more efficient, which allows them to use simpler tech that doesn't need to scale as well.
You are also underestimated the throughput the system needs to handle. 2000 stores * 10 registers per store * 1000 scans per register per hour = 5000 scans per second.
