Loyalty Programs, Retail Purchase Data, and NYC Congestion Pricing

Retail Loyalty Programs

What They Collect

Item-level purchase data: every SKU, timestamp, store location, payment method. Tied to customer profile (name, address, phone, email).

Major Programs

  • Kroger Plus
  • CVS ExtraCare
  • Walgreens myWalgreens (formerly Balance Rewards)
  • Over 90% of US grocery spending linked to loyalty accounts

Data Monetization

Kroger Precision Marketing (84.51°): monetizes purchase data by selling targeted advertising. CVS and Walgreens similarly leverage for ad targeting. Data brokers (Oracle Data Cloud/Datalogix, Nielsen, IRI) historically purchased or partnered with retailers for transaction-level data.

Amazon

Retains purchase history indefinitely. Used for recommendations, ad targeting across Amazon advertising network, sold in aggregate via Amazon Marketing Cloud.

Law Enforcement Access

Loyalty data obtained via subpoena without warrant. Notable case: 2002 murder investigation of Robert Durall (Washington state) — Safeway Club Card records subpoenaed to show purchases of items used in crime.

NYC Congestion Pricing

Launch

January 5, 2025. ALPR cameras at every entry point to Manhattan south of 60th Street.

Data Collected

License plate images, timestamps, entry points for every vehicle. E-ZPass transponder data also collected. MTA oversees program; Conduent Inc. operates tolling technology.

Privacy Concerns

NYCLU raised concerns about mass surveillance implications: blanket ALPR coverage creates searchable record of vehicle movements. Questions about data retention periods and law enforcement access to tolling database.
