Control iD PET UHF Windshield Tag — Vehicle Tag for iDUHF / iDUHF Lite Readers in Chicago

Control iD PET UHF Windshield Tag

The Control iD PET UHF Tag is a passive UHF vehicle tag in PET adhesive-sticker form factor — applies to the inside of the vehicle windshield and reads up to 10 meters on Control iD’s iDUHF and iDUHF Lite access controllers. The right vehicle tag for Chicago commercial parking garages, multi-tenant residential gates, and gated commercial perimeters where the property has standardized on the Control iD UHF reader infrastructure.

Co-Existence with iPASS / E-ZPass Toll Transponders — Vidimost Field Experience

A common concern in Chicago: does this UHF tag interfere with the Illinois Tollway iPASS / E-ZPass transponder I already have stuck to my windshield?

In Vidimost’s field experience installing iDUHF + PET UHF Tag systems across Chicago commercial properties, the answer is no — the two tags co-exist on the same vehicle without operational interference at toll plazas or property gates. The technical reasons (without overstating the manufacturer claim — Control iD’s product page does not explicitly address iPASS interference):

1. Each reader filters by its own EPC database. The iDUHF reader at a property gate only authenticates known EPC IDs registered in the property’s Control iD database. The iPASS reader at a toll plaza only authenticates EPC IDs registered with the Illinois Tollway. Even if both tags happen to be in range of the same reader’s RF field, only the matching EPC gets a positive response.
2. Property gates and toll plazas are physically far apart. Vehicles are rarely within 10 m of both reader systems simultaneously.
3. The PET UHF tag’s small form factor and placement (typically rear-view-mirror area, behind / beside the iPASS transponder) keeps both tags physically separated on the windshield without one shadowing the other.

This is field observation, not a manufacturer guarantee — sites with unusually dense RF environments or specialized toll-plaza configurations should verify behavior at commissioning. But for the typical Chicago commercial multi-tenant property, residential garage, and HOA gate, the co-existence holds reliably across hundreds of vehicles.

How Many Tags Per Vehicle

Each authorized vehicle gets one PET UHF tag registered to a specific user / unit / vehicle in the iDUHF reader’s database. The reader holds up to 200,000 user records locally, so a single iDUHF or iDUHF Lite covers a building-scale population without database expansion.
