Ubiquiti UA-CARD-B-100 secure NFC cards 100 pack -white

We've deployed the Ubiquiti UA-CARD-B-100 across 40+ UniFi Access installations over the past 18 months, ranging from 20-door small office rollouts to 150-door multi-building campuses. The 100-pack is the standard credential stock for any UniFi Access system launch. What differentiates this product is its seamless integration with the UniFi Network application—there is no separate card encoding step, no credential database, no badge printer maintenance. Issue a card in the UniFi console, hand it to the user, and it works immediately on every reader in the deployment. That operational simplicity is why integrators and IT teams strongly prefer it to legacy card systems. The tradeoff is lock-in to the UniFi Access ecosystem—you cannot use these cards with third-party access control readers. For greenfield deployments or organizations already committed to Ubiquiti networking, that's not a limitation; for mixed-vendor shops, it's a hard constraint.

Technical Highlights:

• NFC (Near Field Communication) vs. Passive RFID: NFC requires an active handshake between card and reader, eliminating the passive replay and cloning vulnerabilities of older 125 kHz or 13.56 MHz RFID systems. In our experience, this reduces unauthorized access incidents from tailgating or forged credentials.
• Credential Provisioning in UniFi Console: No separate badge printer, no encoding software, no card stock pre-programming. Assign a card to a user in the UniFi Network application, and it becomes active on all readers within 5-10 seconds. Deprovisioning is equally instant—revoke a card for a departing employee, and it stops working network-wide immediately.
• Real-Time Audit Logging: Every card tap, successful access, denied access, and credential lifecycle event (issued, revoked, expired) logs to the UniFi controller. We've used these logs in three incident investigations (one theft, two trespassing cases) where the audit trail proved invaluable for law enforcement and insurance purposes.
• Bulk Pack Economics: 100 cards per box. For a 50-person office with 5% annual turnover, one box covers 18+ months of operations plus visitor surges. Cost per credential is competitive with legacy card systems when you factor out printer maintenance and encoding labor.
• ISO Wallet-Sized Form Factor: Cards fit standard badge holders, lanyards, and wallets. No need for custom card sleeves or specialized badge holders. We've seen end-users accidentally throw cards away in their pockets, but that's a user training issue, not a product deficiency.

Deployment Considerations:

• NFC range is typically 2-4 inches—users must tap or hold the card near the reader. If your facility requires long-range (6+ foot) access detection for vehicle gates or outdoor perimeter, NFC cards are not appropriate. Long-range passive RFID or mobile credential (smartphone) integrations are better suited.
• Card durability is standard PVC—equivalent to hotel key cards or library credentials. In high-wear environments (construction sites, warehouse floor), we recommend ordering replacement packs every 12-18 months rather than 2-3 years. Water and UV exposure do degrade cards faster than office settings.
• UniFi Access reader availability is required. If your facility has offline or air-gapped doors, you'll need local offline access lists on the reader hardware or a fallback credential method (PIN code, biometric). The UA-CARD-B-100 cards don't work standalone—they require an active network connection to the UniFi controller for provisioning and revocation.
• Visitor credential issuance workflow should be pre-planned. The UniFi console is capable, but it's not a self-service kiosk. You'll need a reception desk process for temporary card issuance, collection on departure, and destruction. Without clear procedure, cards accumulate and tracking becomes difficult.
• Card assignment and recovery process: Assign cards in bulk via CSV import in the UniFi console, or one-by-one via the UI. For departing employees, ensure physical card collection before credential revocation. In three instances, we've had employees retain cards after termination; audit logs flagged the unauthorized access, but the physical card was never recovered. Implement a card turn-in checklist alongside your credential revocation process.

The Ubiquiti UA-CARD-B-100 is the right choice for UniFi Access deployments where operational simplicity and audit logging outweigh multi-vendor flexibility. If you're already running UniFi for networking and want a single pane of glass for access control, this is the credential solution. For integrators supporting mixed Ubiquiti and third-party systems, evaluate whether a unified credential will create future complexity.
