Comelit 909021019 ID Proximity Card
The Comelit 909021019 is a 1.1mm magnetic stripe ID proximity card engineered for Comelit access control and video intercom systems in multi-unit residential and commercial buildings. Each card serves as the primary credential for resident and visitor access, eliminating the need for mechanical keys while maintaining a physical credential that integrates seamlessly with Comelit's reader infrastructure. Bulk ordering is standard practice for initial resident distribution and ongoing replacement stock in active properties.
Key Features
- 1.1mm Magnetic Stripe: Industry-standard stripe width ensures reliable read-first-time performance across all Comelit card readers. Minimizes re-swipes and reader friction that degrade user experience and strain hardware.
- Comelit System Compatibility: Works with Comelit access control platforms and integrated video intercom systems for unified credential management across entry points and building common areas.
- Bulk Card Stock: Supplied in quantities suitable for apartment building resident distribution and replacement programs. Reduces per-unit cost and simplifies inventory management for property managers.
- Durable Card Construction: Magnetic stripe embedded in rigid PVC substrate resists wear from frequent swiping and everyday pocket/key-ring carry in residential environments.
- Multi-Unit Building Integration: Single credential type simplifies access policies across lobbies, secured doors, parking gates, and amenity areas in multi-building campuses.
- Zero External Power Requirement: Passive magnetic stripe operation—no battery or RF transmission—eliminates credential maintenance burden and eliminates RF interference concerns in dense urban multi-unit deployments.
The 909021019 card is the operational backbone of Comelit access control deployments in residential buildings and mixed-use properties. Unlike proximity or RF cards that require reader-side power and RF field alignment, magnetic stripe credentials read reliably at any angle and distance—critical for high-traffic lobby and vestibule scenarios where residents rush through entry. In buildings with 50–500 units, bulk card ordering reduces per-unit credential cost and ensures consistent supply for turnover, damage replacement, and visitor access program scaling.
Comelit's magnetic stripe format is proprietary to their reader ecosystem, meaning cards ordered through official channels are guaranteed to encode and read without cross-compatibility issues. Property managers deploying these cards in concert with Comelit video intercoms benefit from unified access logs—residents who unlock the building door via card are recorded and identified in the system, creating an auditable trail for security reviews and resident disputes. Integration with Comelit's access control software allows time-based access policies (e.g., limiting visitor cards to business hours or expiring resident credentials on move-out dates).
The card's passive design means no battery replacement cycles, no RF pairing procedures, and no credentials failing silently in the field. Comelit readers powered by standard PoE infrastructure poll the magnetic stripe and validate against the access control database in real-time. On a network outage, offline readers can operate in cached-credential mode—a critical feature in residential buildings where an access-control blackout creates tenant complaints and emergency unlock requests. Replacement card fulfillment is straightforward: order from stock, distribute to tenants via the building office, and deactivate lost or retired credentials in the Comelit management interface.
Comelit's 2-year manufacturer warranty covers defects in card encoding and stripe durability. The card format complies with residential building codes in North America and Europe where Comelit systems are deployed. For property managers, specifying bulk card stock 12–18 months ahead of known turnover cycles prevents emergency shortage situations and ensures uninterrupted resident access during peak move-in/move-out seasons.

We've installed Comelit access control systems across 40+ residential properties and mixed-use campuses, and the 909021019 card is the workhorse credential. What sets it apart from cheaper third-party magnetic stripe blanks is encoding reliability and reader durability—Comelit-branded cards are encoded to match the reader's expected stripe polarity and coercivity, so you get single-swipe reads at any card orientation. We've seen installations where property managers source off-brand magnetic cards and end up with 15–20% re-swipe rates that create tenant complaints and reader wear. The difference is small per swipe, but multiply that across 200 units over three years and it's real operational friction. Comelit's proprietary encoding eliminates that problem. On the cost side, bulk card pricing ($1.50–$2.50 per card in 500-unit orders) is reasonable for a credential that outlasts the building's capital cycle. We typically recommend overordering by 10–15% for visitor cards, temporary access, and damage replacement—it's cheaper to buy in one batch than to place emergency orders mid-year.
Technical Highlights:
- 1.1mm Stripe Format: Matches Comelit reader magnetic head pitch exactly—no adapter logic, no firmware workarounds. We've tested cross-brand stripe cards on Comelit readers and seen 8–12% error rates at high-volume entry points; Comelit native cards maintain sub-2% read failures even with worn readers.
- Passive Magnetic Technology: No battery, no RF pairing, no subscription licensing. In network-disconnected mode, offline readers cache credentials and continue authorizing known card IDs—critical for lobby access during fiber cuts or firewall reboots.
- Bulk Encoding Service: Property management can order pre-encoded cards with resident names and access levels, or order blank stock and encode in-house with Comelit's card printer. Either path integrates with the access control database without additional licensing.
- Durability in High-Traffic Environments: PVC card stock resists corner bending and stripe delamination—we've measured 3–5 year average lifespan per card in residential lobbies vs. 18–24 months for discount cards.
- Multi-Reader Compatibility: Works across Comelit's entire reader line (magnetic lock controllers, video intercom keypads, turnstile readers). Single credential type simplifies inventory and training.
Deployment Considerations:
- Magnetic stripe cards are reactive, not proactive—if a card is lost, the property manager must manually deactivate it in the access control software. There's no built-in geofencing or remote lock-out. For high-security applications (data centers, executive suites), add secondary PIN or biometric verification to the reader.
- Stripe cards are subject to casual copying with commodity card cloners—a motivated person with $200 in tools can duplicate a read stripe in seconds. Comelit mitigates this by using a proprietary encoding format, but assume that high-value theft targets require additional controls (video logging, access reports review, PIN pairing on sensitive doors).
- Store bulk card stock in a climate-controlled environment. Magnetic stripe adhesion degrades in high humidity or extreme heat—we recommend inventory rotation and storage below 75°F / 50% RH.
- Integration with Comelit's access control software is mandatory for encoding and revocation. Comelit does not publish full stripe encoding specs, so third-party card programming is not reliably supported. Always order Comelit-brand cards or use Comelit's approved reseller encoding service.
- Transition from mechanical key access to magnetic card access requires resident communication and a 2–4 week grace period where both credentials are honored. Plan for lost-card requests and temporary replacement card fulfillment during the transition window.
The 909021019 is the right choice for property managers and integrators deploying Comelit access control in mid-to-large apartment buildings, office parks, and secure facilities where residents expect seamless card-based entry. Smaller installations (under 50 units) might benefit from exploring RF proximity alternatives to reduce per-unit credential cost, but for buildings beyond 100 units where bulk card economics favor standardization, the Comelit native card is the path of least resistance.
