OSDP readers for secure access control deployments

With 30 years of experience building RFID products, we deliver durable, flexibly-configurable, OSDP and OSDP v2 readers to open OSDP protocol compliant identification systems. With a variety of interfaces, Idesco OSDP readers are compliant with multiple systems. When you choose an Idesco OSDP / OSDP v2 reader, you will also get a supremely reliable, durable device that enjoys the same first-class level of customer support regularly praised by all our other customers. All Idesco's readers - including OSDP - are manufactured in the EU.

OSDP protocol

OSDP (Open Supervised Device Protocol) is an open data transfer protocol supporting bi-directional data transfer between reader and host. OSDP is an open protocol which means compatible devices supporting this protocol are available from several suppliers. OSDP has been developed by SIA (Security Industry Association). New OSDP v2 provides also secure channel communication covered by 128-bit AES encryption.


OSDP v2 is a very secure, bi-directional data transfer protocol, via security channel covered by 128-bit AES encryption which is impossible to hack. System developers enjoy flexible installation provided by OSDP with less cable connections, enabling multi-drop installations for central management of devices. OSDP allows you to use and develop your system flexibly, e.g. easily expand it with new functionalities and devices. In reader-host communication, bi-directional OSDP protocol enables personalized feedback from the system to its user. If your OSDP reader has a display, you can utilize OSDP's text support enabling you to send personalized messages to system users, e.g. notification of an approved / disapproved transponder and the reason for disapproval. 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.
