Question
What is the difference between the two different types of iClass keypad readers that are available?
Answer
- ARD-RK40-09
This reader is in 8-bit unbuffered output mode. Basically, every key pressed outputs 8 bits of data. This is useful for applications that use multi-factor authentication. This would include Readykey Pro, BIS, Access Easy Controller, and Access Professional Edition. Multi-factor authentication requires a card and pin-code to gain entry. This is important because the card is a physical object (for example, something you have), while the pin-code is a mental object (for example, something you know). Most systems described here allow for either single-factor or multi-factor authentication using the ARD-RK40-09.
- ARD-RK40-14
This reader is in 26-bit buffered output mode. This reader would primarily be used in access control on the intrusion series of panels using the D9210B Weigand interface module. This mode only allows for a single-factor of authentication. This reader is useful in applications that require convenience of entering a code from a keypad (for example, the card was left at home). This reader simply outputs a standard 26-bit Weigand string to simulate a card read. Typically, the facility code is set to zero.
Note: These readers will read only iClass smart cards. The ARD-RK40-14 should only be used with standard 26-bit iClass cards.
