Ubiquiti UA-G3-FLEX-B NFC Card Reader with Keypad
Overview
The Ubiquiti UA-G3-FLEX-B is a wired NFC proximity reader purpose-built for enterprise and mid-market access control deployments. It combines NFC and Bluetooth 4.1 credential scanning with a 12-button keypad and native Apple Touch Pass support, enabling multi-factor entry workflows without proprietary mobile app requirements. The weatherproof enclosure handles outdoor and covered indoor installations, making it flexible for building entry points, server rooms, and secured warehouse zones.
Key Features
- NFC and Bluetooth 4.1 proximity reading: Supports Mifare card formats and modern mobile credentials. Bluetooth 4.1 means compatible NFC-enabled smartphones and wearables can unlock without carrier data or WiFi, reducing dependency on network connectivity at the door itself.
- 12-button capacitive keypad: Adds PIN code authorization for secondary authentication. Multi-factor entry — credential + PIN — forces attackers to compromise both the physical card/phone and the PIN, a meaningful security step for high-value access points.
- Apple Touch Pass native support: Eliminates the need for a separate Ubiquiti mobile app for iOS users. Apple Wallet integration means employees already familiar with Apple Pay can authenticate immediately — reduces training and adoption friction in large deployments.
- Weatherproof enclosure: Rated for outdoor and semi-exposed mounting. Rain, dust, and temperature swings won't degrade the electronics — essential for building perimeters, loading docks, and vehicle gate stations.
- Keyfob and PIN-based authorization: Supports both contactless fob unlock and keyboard entry. Flexibility means a single reader can accommodate employees who prefer fobs, mobile credentials, or PIN-only access depending on their role or preference.
- Wired connectivity to UniFi controller: The UA-G3-FLEX-B connects directly to a UniFi network controller via Ethernet, not WiFi. Wired reduces latency and eliminates wireless interference at the access point — critical for high-traffic entries where response time matters.
Integration and Compatibility
The UA-G3-FLEX-B integrates exclusively with the Ubiquiti UniFi access control platform. If your facility already runs UniFi networking or cameras, adding this reader extends the same credential and audit log infrastructure across both systems — a significant advantage for centralized access policy management. Mifare card support means compatibility with existing badge stocks; migration from legacy readers typically requires no physical card replacement.
Deployment requires a wired Ethernet connection to an on-site or cloud-hosted UniFi controller. For sites without existing UniFi infrastructure, budget for a PoE switch or separate controller appliance. Mobile credential activation (Apple Touch Pass and NFC smartphone unlock) requires enrollment through the UniFi dashboard; once provisioned, unlock requests are processed locally, not cloud-dependent.
Deployment Context
Choose the UA-G3-FLEX-B when you need weatherproof, multi-credential access at a single door or small cluster of entry points (under 10 readers per facility). The keypad handles PIN workflows, and Apple Touch Pass support removes friction for smartphone-first environments. If your facility requires more than 50 readers, complex scheduling rules, or deep third-party PACS integration (e.g., Genetec, Salto), evaluate enterprise-class access control systems — they offer more granular policy and redundancy.
Frequently Asked Questions
Q: Does the UA-G3-FLEX-B work without an internet connection?
A: Yes. Once a user credential is enrolled in the local UniFi controller, the reader processes unlock requests on-site. Internet is required only for initial enrollment and cloud backup of audit logs; the door itself will not fail if your WAN link drops.
Q: Can I use the UA-G3-FLEX-B with Android phones?
A: Yes, via standard NFC. Android devices with NFC capability can unlock using Mifare card emulation. Apple Touch Pass is exclusive to iOS, but NFC fallback ensures Android users are not locked out.
Q: Is the UA-G3-FLEX-B IP67 rated?
A: The reader is weatherproof and suitable for outdoor installations. Consult the datasheet for the exact IP rating and temperature operating range for your climate zone.
Q: What power does the UA-G3-FLEX-B draw?
A: Power specifications and PoE compatibility details are listed in the manufacturer datasheet. Confirm with your network switch capacity before ordering multiple units.
Q: Can I integrate the UA-G3-FLEX-B with a third-party VMS or access control system?
A: The UA-G3-FLEX-B is designed for UniFi platform integration. Third-party system integration requires ONVIF or API support from the host system; direct integration with non-Ubiquiti platforms is not documented.
Q: Does the UA-G3-FLEX-B log all access attempts?
A: Yes. All credential reads and access grant/deny events are logged in the UniFi controller with timestamp and user identity. Audit logs can be exported for compliance reporting.

The Ubiquiti UA-G3-FLEX-B sits in a practical middle ground for small to mid-market access control: it's weatherproof, supports modern credentials (NFC + Bluetooth 4.1 + Apple Touch Pass), and integrates cleanly with UniFi infrastructure if you're already running that ecosystem. The 12-button keypad and native Apple Touch Pass support are the real differentiators here — they eliminate the need to push a proprietary mobile app to every user.
Technical Highlights:
- Multi-credential support (NFC, Bluetooth 4.1, keypad): Single reader handles Mifare cards, NFC-enabled phones, Apple Wallet credentials, and PIN entry. This flexibility means you're not locked into one credential type — employees can unlock via whichever method they have on hand.
- Native Apple Touch Pass: Zero friction for iOS users — no app download, no separate provisioning. In large deployments, this reduces help-desk calls and accelerates time-to-productive access.
- Weatherproof enclosure with local processing: Outdoor-rated hardware + wired Ethernet connection means the reader can process unlock requests locally even if cloud connectivity drops. Critical for building perimeters and loading docks where network uptime varies.
Deployment Considerations:
- UniFi-only integration — if your facility runs a different access control platform (Genetec, Salto, etc.), this reader won't play. Confirm controller compatibility before design.
- Wired Ethernet required — no WiFi fallback. You'll need PoE infrastructure at each reader location, which adds cost if you're retrofitting existing entry points without nearby data drops.
The UA-G3-FLEX-B (often searched as UA G3 FLEX B) is well-suited for growing organizations already invested in UniFi — office parks, industrial facilities with a few secured zones, and campuses where credential consistency across door readers and network appliances simplifies management. Skip it if your team spans multiple access control vendors or if you anticipate scaling beyond 20–30 readers; larger deployments benefit from purpose-built PACS with multi-vendor reader support and geographic redundancy.
