Geovision 81-MK135-1F2 MIFARE 13.56MHz ID Tag
Overview
The Geovision 81-MK135-1F2 is a contactless MIFARE ID tag operating at 13.56MHz, designed for access control and personnel identification in multi-user environments. This tag stores secure credentials and pairs with compatible MIFARE readers to authenticate users without physical contact—a practical choice for high-traffic entry points where card readers are already in place.
Compatibility
The 81-MK135-1F2 integrates with Geovision access control systems and any third-party reader that supports standard MIFARE 13.56MHz protocol. Confirm your access control panel or reader supports MIFARE technology before deployment; not all systems recognize this frequency or encryption standard. The tag is commonly embedded in keychains, card stock, or wristbands depending on your credential form factor preference.
Installation Notes
No special wiring or power is required—this is a passive RFID tag. Simply enroll the tag's unique identifier (UID) into your access control system's database and assign it to the user account. Read range is typically 4–10cm depending on reader antenna design; position credentials within that distance of the reader for reliable operation. Store tags away from strong magnetic fields or metal shielding that can degrade signal strength. Encrypted MIFARE storage prevents cloning with standard tools, but always follow your organization's credential issuance and revocation procedures.
