Weaponized Readers
Doppelgänger Core and Stealth are purpose-built longrange card readers that operate autonomously and sync collected cards to ATLAS over WiFi.
Device Types
Section titled “Device Types”Doppelgänger Core
Section titled “Doppelgänger Core”Longrange reader designed for covert card collection at extended range.
Capabilities:
- Autonomous card collection (stores up to 1000+ cards)
- WiFi sync to ATLAS
- Email notifications for new card captures
- GPIO output for external triggers
- Reset card configuration
- Web-based administration
Doppelgänger Stealth
Section titled “Doppelgänger Stealth”Decoy readers purpose-built for physical penetration testing. Stealth and MFAS devices capture credential data and store it locally for later import into ATLAS. They support HID, Indala, AWID, Avigilon, Paxton, and more. HID variants are multiCLASS capable, and MFAS models capture PIN data in addition to card data.
Capabilities:
- Captures credentials when users attempt to badge
- MFAS captures PIN data
- Configurable stealth card response
- WiFi sync to ATLAS
- Battery or wired power options

- Discovered devices appear in the list
- Tap Save to remember a device for future connections
Importing Cards
Section titled “Importing Cards”Import captured cards from your reader to ATLAS:

Operational Considerations
Section titled “Operational Considerations”- Network Requirements — Reader and ATLAS device must be on the same WiFi network
- Card Storage — Devices store cards locally until imported
- Wipe After Import — Consider wiping device storage after importing to prevent duplicate imports
- Mission Signature — Use wired connections when stealth is critical (avoid radio emissions)
