Understanding the Full-Body Scanner: how it works and how to request an exception
Missouri uses the Intercept full-body scanner as part of its front-end security screening. It works alongside walk-through metal detectors, hand-held wands, and X-ray baggage scanners. The goal: spot anything concealed on a person or in their belongings before they enter the facility.
Reminder: When you enter prison grounds, you, your packages, your children, and your vehicle are subject to search. Metal detectors are used at all facilities.
The baseline rule is straightforward: if you're 18 or older, you'll go through the Intercept full-body scanner. The only way around it is having an approved exception on file.
Exceptions are typically approved for a verified medical condition or pregnancy. "Verified" is key here - staff need documentation that supports why you can't be scanned. They're not asking for personal details to be difficult; they just need something on paper.
Exception requests aren't just for family visitors. Vendors, contractors, and other non-staff members can submit one too. These requests go to the facility warden or superintendent, so start the process before you show up - not at the gate.
- Reach out before your visit - Contact the facility in advance so you can ask how to submit a scanner exception request to the warden or superintendent.
- Explain what you’re requesting and when you’re visiting - Share your name and the date you’re trying to come in, and tell staff you’re requesting an exception to the Intercept full-body scanner.
- Ask what documentation is needed and where to send it - The facility will tell you what “verification” they require and what timeline to expect for a decision.
- ✓ A physician statement or other medical verification supporting the exception (including pregnancy, if applicable)
- ✓ Documentation for special medical equipment (for example, a walker, wheelchair, or surgically implanted metal hardware)
- ✓ Any needed medications or life-maintaining medical supplies in original containers and only in the necessary dosage for the visiting period
- ✓ If you plan to bring infant supplies or other allowed items, a note to notify staff in advance so they’re aware of your needs
- ✓ Coins for vending machines in a clear sandwich bag or transparent plastic pouch (if you’ll use vending)
Tip: Bring your physician documentation up front. Exceptions are based on verification, and having paperwork ready can prevent delays at the gate.
Even with an exception, you'll still go through security screening. The Intercept scanner is just one tool. Facilities also use walk-through and hand-held metal detectors, X-ray baggage scanners, and physical searches of visitors and their belongings. The goal stays the same: detecting concealed items before anyone enters.
Warning: If you refuse required screening or staff believe you’re trying to bring in concealed items, you can be denied entry under the facility’s search procedures.
