This research is verified for the main employer-facing point: buddy punching is a time-record problem, but some ways of stopping it can create a bigger privacy-law problem. The research accurately explains why biometric clocks are legally different from lower-risk controls such as GPS context, device checks, photo-on-punch for human review, manager approval, and exception patterns.
The Illinois BIPA section is current as of May 30, 2026. The 2024 amendment limits recovery for repeated Section 15(b) and 15(d) violations to one recovery per person, per method. The Seventh Circuit's 2026 Clay decision says that remedial change applies to pending cases. That changes damages exposure. It does not remove the notice, consent, retention, disclosure, and care duties that make biometric time clocks a serious decision for employers with Illinois workers.
The research also keeps the FLSA recordkeeping point in the right place. If an employer's time records are inaccurate, the employer can lose the clean record it needs in wage disputes. That is why the practical recommendation is not "spy harder." It is to keep better punch records, preserve correction reasons, and use non-biometric review signals before moving to biometric collection.
The only weaker item is the common "2% payroll loss" estimate. The research treats it as directional background rather than as a primary-source claim, which is the right treatment. The page does not build its recommendation on that number.
