Anything that operates by "contactless chip" can also read a chip in the right hand or forehead.

Its purpose is to regulate access by comparing a person's name against a "white list" of people allowed to enter, or a "blacklist" of those who are barred from entry. The person's information is usually contained on a contactless card. The system is also capable of handling biometrics, such as fingerprints.

While it can control a gate–it can be wired in such a way that when the card is approved, a gate opens up–its primary purpose would be to control access with or without a physical gate.

... connected to the portable access monitoring system (within the ruggedized ‘suitcase’). Approved emergency personnel, who have been pre-registered into the system as well as those that are registered onsite, authenticate themselves to the system on entry and/or exit. This can be done using a contactless card or token, a biometric, a PIN, or some combination of these items.

"We created it to have it installed at the front gate to a school, or a stadium, or on a bus. One of the earliest commercial solutions we offered was tracking students from the time they got on the bus until they got off the bus. Called EduGate, it evolved from there because it was a versatile device and it was rugged."
