Simple version
SmartChek is built around a clear idea: the camera at an entry point can do more than record video. It can recognize a secure credential, help verify the visitor's identity and wellness, and support a decision to admit, alert, or escalate.
The pending continuation applications are directed to additional implementations and functionality involving wearables, smart cards, RFID, AI-assisted review, and building-entry access control. These pending claims are separate from the granted Claims 1–17 and remain subject to USPTO examination. That gives Safety Shield Products a broader licensing story than a single doorbell feature.

From visitor arrival to access decision.
The SmartChek pathway turns a camera-equipped entry point into an active credentialing layer. Visitors share only what they choose. Occupants see only what they need to decide.
Step 01Visitor arrives
A visitor approaches the entry point — front door, lobby, healthcare check-in, or commercial small business access portal.
Step 02Visitor selects what to share
On the SmartChek-enabled app or wearable, the visitor chooses which credentials to send: digital identity, stored and/or real-time health information, service authorization — at their discretion.
Step 03Wearable transmits
Real-time health data from a wearable — body temperature, vital signs, wellness markers — can be connected to the visitor’s mobile health app to provide this important safety information to a building occupant through a secure machine-readable code (QR) prior to entry.
- Step 04
Occupant decides
The decoded credential surfaces on the occupant’s phone, tablet, wall panel, or TV. They make an informed, contactless access decision prior to entry.
An informed decision before the door opens.
Personal identification, health details, and optional credentials are decoded from the QR Code and surfaced on the occupant's device of choice — smart home panel, TV, tablet, or phone. Contactless. Real time. Their call.

What SmartChek Does
Same camera hardware
A Safety Shield Products technologySmartChek is not just a scanner. It is a patent-backed way to turn cameras at entry points into credential-recognition and visitor-verification tools. The same idea can support access control, visitor records, and wellness awareness.
Verify the visitor
The optical camera from a video doorbell or home security system reads a secure QR code from the visitor. The system translates the visitor’s personal and health data for the building occupant — confirming the visitor’s ID and wellness before access is granted, denied, or escalated.
Create a trusted visit record
The visit becomes a structured record: who arrived, when they arrived, and what credential and/or health data was presented. That record can connect to access-control and visitor-management systems.
Add wellness awareness
SmartChek technology enables the visitor to share real-time health data from their wearable, stored health information from a mobile health app, and/or health records retrieved from a remote HR or health record database. This creates a comprehensive wellness-awareness layer without replacing existing camera hardware.
Real-time Health Data. Shared.
Extending mobile healthExtending mobile health into real-world protection.
SmartChek extends wearable and mobile health ecosystems into intelligent access and security environments — turning the moment of entry into a consent-based, real-time wellness checkpoint.

What the Patent Protects
U.S. Patent No. 11,984,222 B2 is an issued patent containing 17 granted claims (Claims 1–17), including three independent claims: Claims 1, 6 and 12. The remaining claims are dependent claims.
Code-at-camera
Smart-home method involving a video doorbell assembly with microphone, speaker, and optical camera configured to scan and read a machine-readable code displayed by a visitor's computing device; visitor information is processed and a notification is provided to the occupant.
Networked visitor detection
Smart-home-network method involving a video doorbell assembly with speaker, microphone, and optical camera configured to scan/read a machine-readable code; the system detects and communicates with a visitor computing device, processes visitor data, compares it with stored criteria, and provides a notification.
Wearable health-data handshake
Method of sharing health data using a smart-home network and video doorbell assembly in which a visitor device acquires real-time body-temperature information from a wearable sensor, generates a machine-readable code containing that information, and displays the code to the optical camera of the video doorbell assembly.
Single-unit video doorbell assembly
Claim 17 depends from Claim 1 and further specifies that the video doorbell assembly is a single unit housing the microphone, speaker, and optical camera, configured to be mounted adjacent to an exterior entrance of a home.
Safety Shield Products also has pending continuation applications directed to additional implementations and functionality. These pending claims are separate from the granted Claims 1–17 of U.S. Patent No. 11,984,222 B2 and remain subject to USPTO examination. The pending applications are directed to wearable-sourced data, RFID/IC-card paths, AI-assisted review, and wellness-awareness patterns. Detailed claim charts and feature mapping are available during private review.

Ways to License or Acquire
License the IP
A company can license the protected technology for use in smart entry, visitor verification, access control, or related credential-recognition products. The structure can be narrow, broad, exclusive, or non-exclusive depending on the buyer and market.
Partner with a platform or OEM
SmartChek can be positioned for companies that already ship cameras, doorbells, building access systems, identity tools, or connected health products. The goal is to add protected capability without asking the market to adopt new hardware first.
Acquire the IP asset
A strategic buyer, IP platform, fund, or private equity group can evaluate a full acquisition of the issued patent, continuation filings, and SmartChek® trademark rights. Supporting materials are available during private review.
Who This Is Built For
Three buyer typesThe asset is designed for buyers who already understand cameras, access control, identity, connected devices, healthcare entry, or licensing. Named counterparties and engagement status are shared only during private review.
Logistics-led consumer platform
Camera install base is already there. SmartChek converts the doorbell from a passive recorder into a verified-credential decision point at the moment of delivery, with an optional wellness-awareness extension for households with newborns, those with weak immune systems, and elderly members.
AI + identity ecosystem
The pending continuation claims map onto AI-assisted evaluation and additional wearable-sourced biometrics. SmartChek is the credential and consent layer that sits between the camera, the wallet, and the health ecosystem.
Access-control SaaS
The access pathway is already core. Wellness awareness extends the same monitored-property relationship into caregiver and senior-housing use cases without new hardware deployment.
