Illinois ID scanning laws

Illinois places specific limits on ID-reading technology and on how information collected from an ID can be used afterwards.

For bars, restaurants, dispensaries and retailers, the important questions are when an ID must be checked, when scanning is required, what you may do with information you collect and when Illinois biometric privacy rules come into play.

What Illinois venues should know

Do you have to check IDs in Illinois, and when?

It depends on what you sell. Scanning is required for cannabis, but not generally for alcohol or tobacco.

Alcohol

Illinois alcohol law requires adequate written evidence of identity and age when proof is requested. The law does not require that check to be performed electronically.

Cannabis

Cannabis dispensaries must use an electronic reader to scan a purchaser's government-issued identification.

Tobacco and vape

Retailers must examine government-issued photographic identification when a customer appears to be under 30. Again, the requirement is to check the ID rather than to use a scanner.

The exact wording

refuse to sell, deliver, or serve alcoholic beverages to any person who is unable to produce adequate written evidence of identity and of the fact that he or she is over the age of 21 years, if requested

235 ILCS 5/6-16720 ILCS 675/1410 ILCS 705/10-20

Which IDs provide protection in Illinois?

Illinois alcohol law is not limited to a short list of specific ID types.

The law describes adequate written evidence as identification issued by a federal, state, county or municipal government. It provides examples, but the list is not exclusive.

That means the focus is generally on whether the customer presents qualifying government-issued evidence of identity and age rather than whether the document appears on a short list of approved credentials. Separate rules can apply to how information from a particular credential is scanned or used afterwards.

The exact wording

a document issued by a federal, state, county, or municipal government, or subdivision or agency thereof, including, but not limited to, a motor vehicle operator's license, a registration certificate issued under the Federal Selective Service Act, or an identification card issued to a member of the Armed Forces

235 ILCS 5/6-16625 ILCS 5/6-117.1

Can you keep data from an ID scan in Illinois?

Yes, but what you can do with that information is limited.

Illinois does not set a general retention period for ID information collected by an alcohol venue. Instead, the law limits how that information may be used.

Information collected from an ID may generally be used to:

  • Identify the person
  • Complete the transaction in which the information was obtained

It may not be reused for unrelated purposes such as commercial solicitation. Illinois also restricts selling, leasing or sharing the information with third parties, apart from specified uses related to detecting or prosecuting crime or fraud.

This matters for repeat visits. Information originally collected for one transaction should not automatically become a reusable customer profile for future visits without the customer's express permission.

Customers can bring a private claim for violations, with statutory damages and legal fees available under the law.

The exact wording

When information is obtained from a driver's license to identify or prove the age of the holder of the license, or in the course of a commercial transaction, that information may be used only for purposes of identification of the individual or for completing the commercial transaction in which the information was obtained

Information obtained from a driver's license may not be used for purposes unrelated to the transaction in which it was obtained, including, but not limited to, commercial solicitations.

625 ILCS 5/6-117.115 ILCS 335/14D

What other Illinois laws reach the data you keep?

Illinois also has data security and biometric privacy rules that may apply depending on what your venue collects.

Keeping someone's name together with a driver's license or state ID number can bring Illinois data-security requirements into play. Biometric information is treated separately.

Illinois's Biometric Information Privacy Act, commonly known as BIPA, covers specific biometric identifiers and information. A photograph by itself is excluded from the statutory definition.

If a business collects a covered biometric, additional requirements apply before collection, including notice, disclosure of the purpose and retention period, and a written release. So simply reading information from an ID barcode is different from separately collecting biometric information from the person presenting it.

The exact wording

[A biometric identifier is] a retina or iris scan, fingerprint, voiceprint, or scan of hand or face geometry.

740 ILCS 14/10740 ILCS 14/15815 ILCS 530/45

Does scanning give you a defense if you serve a minor in Illinois?

No. For alcohol, using a scanner does not itself create the statutory protection.

Illinois protects an alcohol licensee who requests identification, is shown adequate written evidence and reasonably relies on it. That protection can apply both to a criminal case and to proceedings involving the alcohol license. What matters is the identification presented and the venue's reasonable reliance on it, not whether a scanner was used.

Cannabis is different. Illinois has separate rules requiring ID scanning for dispensaries and provides protections specific to that process.

The exact wording

Proof that the defendant-licensee, or his employee or agent ... demanded, was shown and reasonably relied upon such written evidence in any transaction forbidden by this Section is an affirmative defense in any criminal prosecution therefor or to any proceedings for the suspension or revocation of any license based thereon. It shall not, however, be an affirmative defense if the agent or employee accepted the written evidence knowing it to be false or fraudulent.

235 ILCS 5/6-16410 ILCS 705/10-20

Can a customer refuse an ID scan in Illinois?

Illinois does not specifically address a customer's refusal to scan a physical ID.

For alcohol, a venue can still require adequate evidence of identity and age where an ID check is necessary. Illinois is more specific about mobile credentials. A business cannot require someone to present a mobile ID instead of a physical credential.

When a customer does use a mobile ID, the business also cannot require them to hand over possession of their phone, and presenting the credential does not give permission to access other information on the device.

The exact wording

No person, public entity, private entity, or agency shall establish a policy that requires an electronic credential instead of a physical credential.

15 ILCS 335/4235 ILCS 5/6-16

Does Illinois biometric privacy law apply to ID scanning?

Reading an ID barcode by itself does not make the scan biometric.

BIPA covers specific biometric identifiers and biometric information, including fingerprints, voiceprints, retina or iris scans and scans of hand or face geometry. Photographs are excluded from the definition. If a venue separately captures a covered biometric, BIPA requirements can apply.

Before collecting it, the business generally needs to:

  • Tell the customer that biometric information is being collected
  • Explain why it is being collected and how long it will be kept
  • Obtain a written release

For venues, the important distinction is between reading information from the ID and collecting biometric information from the customer.

Alcohol, cannabis and tobacco

Alcohol

Illinois focuses on checking and reasonably relying on qualifying identification.

The alcohol law does not require ID scanning. Instead, its protection is based on requesting proof, being shown adequate written evidence and reasonably relying on that evidence. Using a scanner can support your ID-checking process, but scanning itself does not create additional protection under the alcohol rule.

235 ILCS 5/6-16

Cannabis

Cannabis dispensaries must scan identification.

Illinois requires dispensaries to use an electronic reader to scan government-issued identification. The dispensary's internal systems must also delete the purchaser's personal information within 24 hours of the purchase. Cannabis therefore has a very different scanning and retention rule from ordinary alcohol venues.

410 ILCS 705/10-20

Tobacco and vape

Check identification when the customer appears to be under 30.

Illinois requires retailers to examine government-issued photographic identification in that situation. The law requires an ID check, but does not require the retailer to perform that check electronically.

720 ILCS 675/1

Records from an ID

The use restrictions apply to more than just barcode data.

Illinois's rules can reach information read from the printed face of an ID as well as information obtained electronically. That means typing information manually instead of scanning it does not necessarily remove the restrictions on how the information may later be used or shared.

15 ILCS 335/14D

What this means for your AgeShield setup

These are the AgeShield settings affected by the Illinois rules above. How you configure them is ultimately a decision for your venue.

How long visits are kept
For ordinary alcohol venues, Illinois does not set a general retention period. Instead, the information remains limited to identifying the customer or completing the transaction in which it was collected. For cannabis dispensaries, purchaser personal information must be deleted from internal systems within 24 hours of the purchase.AgeShield setting: Set your retention period based on how long your venue needs the information for the purpose for which it was collected.
Records that carry across visits
Using information from one visit to recognize a customer during a later visit goes beyond the original transaction.AgeShield setting: If your venue wants a guest record to carry across visits, use the consent flow to obtain the customer's express permission.
Consent screen
Illinois allows express permission to support uses of ID information beyond the original transaction.AgeShield setting: Enable the consent screen when your venue wants to obtain that permission, and make clear what the information will be used for.
Which ID fields are stored
Illinois's use restrictions can apply to information taken from both the barcode and the visible face of an ID.AgeShield setting: Choose which ID fields are collected and stored based on what your venue actually needs.
Banned lists and sharing
Illinois restricts selling, leasing and sharing ID information with third parties, subject to limited exceptions such as crime or fraud prevention.AgeShield setting: Review whether list information stays within your own venue or is shared with other locations or third parties.
Biometric features
Illinois has separate rules when a business collects covered biometric information.AgeShield setting: If your venue uses a feature that collects a covered biometric, treat that separately from the ID scan and make sure the required notice, purpose and retention disclosure, and written release are in place.

Common questions

Is it legal to scan IDs at a bar in Illinois?

Illinois does not treat every form of ID scanning the same way. It specifically restricts technology designed to read encrypted information from Illinois-issued driver's licenses and state IDs, subject to statutory exceptions.

Do I have to scan IDs in Illinois?

For ordinary alcohol sales, no. Cannabis dispensaries must use an electronic reader, while tobacco retailers must check photographic identification when a customer appears under 30.

How long can I keep ID scan data in Illinois?

For an ordinary alcohol venue, Illinois does not set a general number of days. Instead, the information may be used only for limited purposes connected to identifying the person or completing the transaction in which it was obtained.

Does scanning give you a defense if you serve a minor in Illinois?

For alcohol, scanning itself does not create the defense. The protection comes from requesting, receiving and reasonably relying on adequate written evidence of identity and age.

Can a customer refuse an ID scan in Illinois?

Illinois does not specifically address refusal of a scan of a physical card. For mobile credentials, businesses cannot require a digital ID instead of a physical one or require the customer to hand over their device.

Does BIPA apply to ID scanning?

Reading an ID barcode alone is not biometric collection. BIPA becomes relevant when a business collects covered biometric identifiers or information. A photograph by itself is excluded from BIPA's definition.

Do Illinois cannabis dispensaries have different rules?

Yes. Cannabis dispensaries must scan government-issued identification, and purchaser personal information must be deleted from internal systems within 24 hours of the purchase.
