OSDP secures your deployment

Our 30 years experience building RFID products ensures our OSDP readers not only interface seamlessly in OSDP-compliant identification systems but will be reliable and secure. Supporting either OSDP v1 or v2 protocols, our readers are explicitly designed for compliance across the widest range of OSDP-protocoled systems. So, when you choose an Idesco OSDP reader, you also get a rugged, reliable device enjoying the same first-class, expert customer support regularly praised by our customers. Like all Idesco readers, our OSDP readers are EU-manufactured and supported.

What is OSDP?

OSDP (Open Supervised Device Protocol) is an open protocol that supports transmission of data bi-directionally, between readers and their hosts (controller and/or system). Originally developed by US-based Security Industry Association (SIA), OSDP was conceived as a communication standard to ensure seamless interoperability between compliant devices sourced from different suppliers. The latest iteration, OSDP v2, has been enhanced to powerfully secure bi-directional data transmission with effectively unbreakable 128-bit AES encryption.

Why deploy OSDP?

The security of OSDP v2, shielded by 128-bit AES encryption, makes it effectively impervious to skimming, let alone hacking attempts. OSDP integrators enjoy unsurpassed design and installation flexibility since the protocol also supports serial multi-dropping of readers and controllers across a single circuit. This greatly simplifies deployment, central management (monitoring, updating) as well as future system expansion with new devices and/or functionalities. An increasingly popular capability the v2 protocol permits is personalized, downstream messaging to users. When a reader possesses a text screen, it can display personalized messages to users (e.g. expiration time of temporary credentials). Two-way communication also enables monitoring of devices in addition of updating and configuring them centrally from your system.

OSDP reader with sunproof display

Idesco OSDP reader with 2,4 inch sunproof colour display provides OSDP v2 data transfer with full text support. It has a mechanical keypad with raised keys and programmable function keys. Keypad backlight increases convenience when using the reader in dark. With this OSDP reader, your system can provide users personalized messages or more detailed, visual feedback about reading events (e.g. access granted / access denied), and e.g. reason for denial. You can utilize display in several ways, e.g. delivering visual instructions to visitors. This OSDP reader with display is a secure choice for outdoor deployments, as it fully dust and moisture proof with IP67 protection class and operates in temperatures from -30 °C to +55 °C.

Unmatched OSDP flexibility

Idesco OSDP readers complement the unmatched OSDP system flexibility with a variety of interfaces and technologies to work with, when planning your reader deployments and OSDP system development. Idesco OSDP readers support open MIFARE® Classic and MIFARE® DESFire technologies. Our tradition of constant development of our readers with new features ensures our readers remain 'future-proofed', providing long life-spans, seamless re-configurability and updatability. This helps you to utilize the full capacity of your flexible OSDP system. We offer OSDP reader housings designed for both door frame and electrical socket siting. Optional installation and insulation plates reduce eddy current interference from metal surfaces or EM-noisy locations. Installation plates also conveniently cover old screw holes left by legacy readers.

LEGIC readers with a variety of interfaces

Durable Idesco OSDP readers

Most Idesco OSDP readers operate in the widest range of temperatures: -40 °C to +55 °C. With protection class IP67 they withstand moisture, frost and dust. They can be even immersed in water, making them very suitable for use outdoors, without any additional covers to deploy. Outdoor sites experiencing frost or snow frequently create problems for pin pad readers by blocking their keypads. However, some Idesco OSDP keypad readers are available without moving keys - ideal for truly inclement sites. When a site might suffer a higher vandalism risk, reader impact resistance can be crucial. That's why our Idesco OSDP readers enjoy the EN 62262 standard's two highest IK scores for impact endurance, enduring impacts of 10 to 20 joules depending on their IK score. All housings are cast from fire-tested polymers enjoying both UL94 HB (horizontal) and UL94 V2 (vertical) inflammation-resistance. Lastly, every reader embeds a tamper alarm, for automatic system detection of attempted dismantling.

RFID modules with OSDP protocol

Idesco RFID module with OSDP interface embeds secure OSDP / OSDP v2 support in your own device or machinery. Idesco's reader modules with OSDP / OSDP v2 interface transforms any suitable device into its own OSDP compliant reader. Its 72 x 37,8 x18 mm dimensions let numerous small devices accommodate it. Modules come with cable, or connector (or neither if preferred). If you manufacture readers, Idesco modules with OSDP / OSDP v2 interface offer you a truly cost-effective way to expand and enhance your offering with OSDP / OSDP v2.
