Yes. California lets bars, liquor stores, tobacco shops and dispensaries scan IDs. You may use scan data only to verify age or ID, meet a recordkeeping law or prevent fraud. Misusing it can bring up to a year in jail.
California changed the rules for ID scanning on January 1, 2026. Under AB 509, a scan now counts as evidence for your business if a fake ID gets through, on top of the checked ID defense you already had. That matters, because one minor served can cost you your liquor license for 15 days.

Can you scan IDs in California?
Yes. California lets bars, liquor stores, tobacco shops and dispensaries scan IDs. For alcohol, a checked ID is your defense if a minor gets served, and a scan now counts as evidence too. Dispensaries must check every customer. The minimum age is 21 for all of them (18 at dispensaries with a doctor’s recommendation), so card anyone who could be under 21, tobacco buyers under 30 and every cannabis customer.
How the scan defense works
If a fake ID passes your scanner, the scan counts as evidence for your business in a criminal case or an ABC license hearing. It applies when:
- The ID is valid proof of age and identity under §25660
- Staff physically inspected it
- It looked legitimate
- It matched the customer’s appearance
Civil Code §1798.90.1 lets you use scan data only to verify age or ID, meet a recordkeeping law or prevent fraud. For the exact wording, see the ABC’s 2025 legislation updates for AB 509.
Which IDs are accepted in California?
You can accept a California or out-of-state driver’s license or ID card, a U.S. military ID or a U.S. or foreign passport, but not temporary paper licenses, DMV receipts, foreign driver’s licenses, school, work or Social Security cards, or any expired, altered or borrowed ID. California’s mobile driver’s license is still a pilot, and the DMV tells holders to carry their physical card.
Fines for selling to minors in California
| Violation | Penalty |
|---|---|
| Alcohol sale to a minor (business) | 15 days, then 25 days, then revocation within 36 months |
| Alcohol sale to a minor (clerk) | $250 fine and/or 24 to 32 hours of community service |
| Tobacco sale to a minor (store) | $1,000 to $1,500, rising to $20,000 or more by the 5th |
| Cannabis sale to a minor | 15 to 30-day suspension and/or at least $1,000 |
| Misusing scanned ID data | Up to 1 year in jail and/or $10,000 |
The ABC and local police run a minor decoy program with decoys under 20. Anyone who serves alcohol or checks IDs needs RBS certification within 60 days of hire. For the full penalty rules, see the ABC’s penalty guidelines and the DCC disciplinary guidelines.
What California IDs look like
- Cards issued since October 1, 2025 have no magnetic stripe, only a PDF417 barcode
- The barcode carries a DMV digital signature that protects its data from tampering
- Under-21 cards are vertical with a red strip showing the year the holder turns 21
See current card designs on the California DMV’s new card design page.

Why California's New Scan Law Makes Scanning Count
Since January 1, 2026, under AB 509, scanning an ID’s barcode counts as evidence in a California business’s favor if a fake ID gets through. That matters because one minor served with a fake ID can cost a venue its liquor license for 15 days, and a third violation within three years means revocation.

Patronscan originated the flag network and has spent years expanding it across North America, Europe, the United Kingdom, and Australia. When a flagged individual walks into any Patronscan-connected venue, staff are immediately alerted. In California, review how flags are shared with your legal team, because state law limits sharing scan data.
The ID Scanner That Puts California's Scan Law to Work
Since January 1, 2026, AB 509 lets a California business use an ID scan as evidence in its favor when a fake ID gets through, if staff also physically inspected the card and it matched the customer. Patronscan is an ID scanner for bars, liquor stores, tobacco shops and cannabis dispensaries, with retention settings you can configure for California’s scan data limits.
