I have read this paragraph several times and I find it quite contradictory.
"A. Networked Contactless Smart Card Readers: Contactless smart cards reader to securely read
access control data from 13.56 MHz contactless smart cards. The contactless smart card reader
is designed for use in access control applications by providing:
1. Secure access control data exchange between the smart card and the reader utilizing key
diversification and mutual authentication routines.
2. Contactless smart card reader to be designed for low current operation to enable
migration from most legacy proximity applications without the need to replace existing
access control panels and/or power supplies. Operating voltage: 5-16 VDC. Current
requirements: 55 mA Avg, 116 mA Peak at 12 VDC.
3. Universal compatibility with most access control systems and backwards compatibility
with legacy 125 KHz proximity access control formats.
4. Product construction suitable for both indoor and outdoor applications.
5. Customizable behavior for indicator lights and audible tones.
6. Acceptable Manufacturers (13.56 MHz iClass):
a. HID Global (HD) - R10/R40 Series."
It's my understanding that a R10/R40 reader will ONLY read iClass.
