When Employers Change How Biometric Data Is Used Without Telling Employees
Many workplaces now use biometric technology to track time, control building access, and verify employee identities. Fingerprint scanners, facial recognition, and voice recognition are common in offices, warehouses, hospitals, and retail settings. Employers often implement these systems to improve efficiency or prevent timekeeping fraud. However, biometric data differs from other workplace information because it is permanent and cannot be changed like a password or ID number. Collecting, storing, or altering the use of biometric data without properly informing employees can create significant legal risks.
Our cybersecurity lawyers often represent individuals whose employers expanded or changed the use of biometric data without proper notice or consent. Employees may have agreed to limited uses, such as payroll timekeeping, only to find their data later used for surveillance, identity tracking, or integration with other systems. Such changes can violate privacy laws that protect workers and their personal information.
What Counts As Biometric Data In The Workplace
Biometric data includes unique physical or behavioral identifiers used to confirm a person’s identity. Employers are increasingly collecting these identifiers through workplace technology systems. Common examples include:
- Fingerprint scans used for timekeeping or building access.
- Facial recognition systems used for workplace entry.
- Voice recognition used for phone or device authentication.
- Retina or iris scans used in high-security environments.
- Hand geometry scans used in manufacturing or warehouse facilities.
Because these identifiers are unique to each individual, they provide a powerful form of identity verification. At the same time, their permanence makes them extremely sensitive. If biometric identifiers are exposed or misused, the affected individual cannot simply replace them.
Why Changes In Biometric Data Use Can Create Legal Problems
Employees often agree to biometric data collection under specific conditions. A company might explain that fingerprints will only be used to track work hours. If the employer later begins using those same fingerprints for surveillance, access tracking, or data-sharing with third parties, the original consent may no longer apply.
Several states have enacted laws governing the collection, storage, and use of biometric information. One of the most widely known is the Illinois Biometric Information Privacy Act (740 ILCS 14). This law requires companies to obtain written consent before collecting biometric identifiers and to clearly disclose how the information will be used and stored. The law also requires companies to establish written policies explaining how long biometric data will be retained and when it will be destroyed.
If an employer changes the purpose for which biometric data is used without informing employees or obtaining new consent, the company may violate these legal requirements. Workers may then have the right to pursue claims for statutory damages and other remedies.
Common Situations Where Employers Expand Biometric Data Use
Many biometric privacy disputes arise when a company quietly expands how employee identifiers are used. Workers may not learn about the change until months or even years later. Several situations appear frequently in workplace cases.
One common example involves integrating biometric systems with new software platforms. An employer may initially collect fingerprints for payroll purposes, but later connect that system to security software that tracks employee movement throughout the facility.
Another situation occurs when companies share biometric data with third-party vendors. Payroll processors, security contractors, and cloud software providers sometimes receive employee biometric identifiers as part of system integrations. If employees were never told their data would be shared externally, this can raise significant privacy concerns.
Employers may also expand biometric data use by linking identifiers to broader employee monitoring systems. For example, facial recognition tools may be combined with video surveillance systems to track employee attendance, productivity, or location within the workplace.
Each of these changes can alter how personal data is used in ways that employees never agreed to.
Why Transparency And Consent Are Legally Important
Privacy laws governing biometric identifiers place strong emphasis on transparency. Employees must be informed about what data is collected, why it is collected, and how long it will be stored. They must also have the opportunity to provide meaningful consent before the data is gathered.
Under the Illinois Biometric Information Privacy Act, companies must provide written notice explaining:
- The purpose of the biometric collection
- The length of time the data will be stored
- When and how the data will be destroyed
Employees must also sign a written release before biometric identifiers can be collected. If an employer later changes how that data will be used, the original disclosure may no longer be sufficient.
Other states, including Texas and Washington, have enacted biometric privacy laws as well. For example, the Texas Capture or Use of Biometric Identifier Act (Tex. Bus. & Com. Code §503.001) requires companies to obtain consent before collecting biometric identifiers and to safeguard that information appropriately.
When employers fail to follow these requirements, employees may have legal grounds to pursue claims.
The Risks Employees Face When Biometric Data Is Misused
When biometric identifiers are used beyond their original purpose, employees face several potential risks. One concern is the possibility of unauthorized tracking or surveillance. Expanded biometric systems may allow companies to monitor employees in ways that were never disclosed.
Another risk involves data exposure. If biometric identifiers are stored improperly or shared with outside vendors, the information could be compromised in a breach. Unlike passwords or ID cards, biometric identifiers cannot be changed if stolen.
Employees may also face long-term privacy concerns when biometric data becomes part of larger databases. Once information is copied, shared, or transferred across systems, it becomes much harder to control how it is used.
Because of these risks, laws regulating biometric identifiers impose strict requirements on employers.
Legal Rights Employees May Have Under Biometric Privacy Laws
Employees whose biometric data was used beyond the scope of their consent may have rights under state privacy laws. In Illinois, the Biometric Information Privacy Act allows individuals to bring legal claims directly against companies that violate the statute.
The law provides for statutory damages of:
- $1,000 per negligent violation
- $5,000 per reckless or intentional violation
Because biometric systems often scan employees multiple times per day, violations may accumulate quickly. Courts across Illinois have seen significant litigation involving timekeeping systems that collected fingerprints without proper consent.
Other states may allow claims under consumer protection laws, employment laws, or common-law privacy theories when biometric identifiers are mishandled.

Frequently Asked Questions About Biometric Privacy
Can My Employer Collect My Fingerprint For Timekeeping Without My Consent?
In some states, employers must obtain written consent before collecting biometric identifiers such as fingerprints. Illinois, Texas, and Washington all have laws governing biometric data collection. Under the Illinois Biometric Information Privacy Act, employers must provide written notice explaining the purpose of the collection and obtain a signed release from employees. If a company collected fingerprints without following these steps, workers may have legal claims.
What If My Employer Started Using My Biometric Data For A New Purpose?
If an employer begins using biometric identifiers for purposes that were not originally disclosed, the company may need to provide new notice and obtain additional consent. Expanding the use of biometric data without informing employees can violate privacy laws, depending on the jurisdiction. Workers who discover such changes should review company policies and seek legal advice to determine whether their rights were affected.
Can My Employer Share Biometric Data With Third-Party Vendors?
Some biometric privacy laws restrict how companies may share biometric identifiers. In Illinois, companies generally cannot sell, lease, trade, or otherwise profit from biometric data. They must also take reasonable steps to protect it and limit disclosure to specific circumstances. If biometric identifiers were shared with outside vendors without proper notice or consent, employees may have legal claims.
What Damages May Be Available In Biometric Privacy Cases?
In Illinois, the Biometric Information Privacy Act allows individuals to seek statutory damages for violations. These damages may be $1,000 per negligent violation or $5,000 per intentional or reckless violation. Other states may allow compensation through consumer protection laws or privacy-related claims. Courts may also order companies to change their biometric data practices.
What Should I Do If I Think My Employer Misused My Biometric Data?
Employees who suspect misuse of biometric identifiers should gather any relevant documents, including employee handbooks, consent forms, or company communications about biometric systems. Understanding what the employer originally disclosed can help determine whether privacy laws were violated. Legal guidance can also help evaluate potential claims and determine whether other employees may have been affected.
