It reads MIFARE DESFire encrypted credentials and communicates over the Open Supervised Device Protocol (OSDP), a modern bidirectional serial standard that supports supervised wiring and encrypted reader-to-controller communication. This reader is installed by security integrators and low-voltage technicians as part of a broader access control system, typically at door entry points in commercial or institutional facilities.\u003c\/p\u003e\n\u003cp\u003eThis reader is suited for commercial access control deployments where credential security and controller interoperability are priorities. OSDP-capable controllers support two-way communication with this reader, enabling real-time status monitoring and firmware updates over the RS-485 bus. DESFire card technology provides AES-based encryption at the credential level, making it appropriate for higher-security installations such as office buildings, healthcare facilities, and government sites.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDESFire credential support with AES-based encrypted card communication\u003c\/li\u003e\n  \u003cli\u003eOSDP protocol for bidirectional, supervised RS-485 communication with access controllers\u003c\/li\u003e\n  \u003cli\u003eDesigned for commercial and institutional access control door deployments\u003c\/li\u003e\n  \u003cli\u003eSold as an individual unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation smart card reader for OSDP-compatible access control panels and controllers supporting DESFire encrypted credentials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage or security systems technician in accordance with applicable local codes and the controller manufacturer's wiring specifications. Power down the access control panel before wiring the reader to the RS-485 bus. Verify OSDP addressing and baud rate settings on both the reader and the controller before commissioning. Do not connect or disconnect wiring while the panel is energized.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Category\u003c\/strong\u003e: Smart Readers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GEOVISION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 520-RKR1355-000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEOVISION","offers":[{"title":"Default Title","offer_id":51559111393586,"sku":"520-RKR1355-000","price":489.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a6d91e49e1d6067db1805578f9381ff.jpg?v=1786427927","url":"https:\/\/voomisupply.com\/products\/geovision-520-rkr1355-000-desfire-osdp-smart-card-reader","provider":"Voomi Supply","version":"1.0","type":"link"}
