Event Record

Urban Grid and Digital Access Control During the Pandemic

Dense governance through health codes, venue codes, community lists, and grassroots dispatch.

Event scope

The record separates public-health necessity during an emergency from long retention, function creep, and weak appeal.

Verifiable timeline

• From 2020 health codes and community grids became core urban epidemic infrastructure.
• Venue codes and testing records further connected identity, location, and access.
• Policy changed rapidly at the end of 2022 and many compulsory interfaces stopped.

Institutions and mechanisms

Health, big-data, streets, communities, police, and commercial venues jointly enforced identity checks and access control.

Government response

Authorities described the systems as epidemic-control tools, while the PIPL set general principles and responsibilities for personal-information processing.

Unresolved questions

Local deletion, vendor retention, and later use lack a unified public audit. ^[1]
