Sdc/Security Door Controls HID1326-100 Proximity Card II

We've spec'd thousands of HID proximity credentials across corporate offices, healthcare campuses, and mixed-use facilities, and the HID1326-100 is the baseline choice when integrators are expanding or maintaining existing HID reader infrastructure. The strength of this credential is its radical simplicity: no batteries, no active electronics, no encoding headaches on-site. You order cards, the manufacturer encodes the unique ID, you receive them pre-programmed, and your ACS admin provisions them in the database. That separation of concerns—manufacturing encoding versus operational provisioning—eliminates a whole class of field errors. On a 200-cardholder campus retrofit, that means zero on-site card encoding equipment, no enrollment delays, and a 48-hour deployment window instead of a two-week roll-out. The lifetime warranty is honest: passive cards don't fail in normal conditions. We've pulled 10-year-old HID proximity cards from retired offices and tested them on modern readers with zero issues. The trade-off is obvious: proximity cards have zero encryption, no biometric binding, and the ID is readable by any 125 kHz reader. If your security posture requires card-to-cardholder mutual authentication or encrypted credential exchange, you need smartcards (HID iClass or DESFire). But for general office access, campus parking, and multi-building perimeter control—where the threat model is honest employees and occasional tailgating, not credential cloning attacks—the HID1326-100 is the right economic and operational choice.

Technical Highlights:

• 125 kHz Passive Proximity: Credential contains no battery or active circuitry—magnetic coil is energized by the reader's RF field. Read range typically 2–6 inches depending on reader antenna design and environmental interference. Eliminates credential replacement cycles driven by battery life.
• HID Proprietary ID Encoding: Credential ID is encoded into the card substrate during manufacturing. Standard HID 26-bit Wiegand format is most common for older systems; newer HID infrastructure supports extended formats (35-bit, 37-bit). Confirm your reader support before large orders.
• TCP/IP ACS Integration: Reader hardware connects to networked access control panels via Ethernet. Card presentation triggers reader to transmit credential ID and reader status to the ACS controller. No intermediate gateway or protocol converter required if reader and ACS are both HID-compatible.
• Bulk Issuance & Rapid Deployment: Pre-programmed credentials ship ready to activate. No field encoding step reduces deployment timeline and training overhead for facility staff.
• Passive Durability: No moving parts, no environmental sensors, no battery aging. Card failure in normal indoor use is extremely rare. Lifetime warranty reflects this reality.

Deployment Considerations:

• Confirm your HID readers support the credential format (26-bit, 35-bit, or extended). Older HID Prox readers may not decode newer card formats. Request reader firmware version and format support from the reader OEM before ordering large quantities.
• Credential ID must be unique across your access control system. If you are consolidating multiple facilities or adding to an existing HID infrastructure, coordinate credential ID allocation with your ACS admin to prevent collisions. Duplicate IDs will cause unpredictable access behavior.
• 125 kHz proximity signals can be read through plastic sleeves, leather wallets, and jacket pockets—but NOT through metal or water-filled containers (e.g. aluminum foil, a filled water bottle immediately in front of the card). Brief the cardholder on presentation technique to avoid false rejects at the reader.
• Proximity credentials are not encrypted. An adversary with a 125 kHz reader can clone the card ID. For high-security applications (data center, government, financial), mandate smartcard technology (HID iClass or DESFire) instead. For standard commercial access control, this is not a material risk.
• Reader mounting height and angle affect detection range. Mount readers 48–60 inches from the floor and perpendicular to the cardholder's expected approach vector. Test card presentation angles during commissioning to confirm reliable detection across left-hand and right-hand presenters.
