1 Having many interface modules per channel decreases the polling rate per interface. This is a consideration if you have PIN readers connected to the same channel in daisy chain. If the readers are configured to output PIN in 4-bit Burst Keypad Mode, decreasing the polling rate per interface might increase the chance of a digit being missed when someone enters their PIN quickly, resulting in a denied access.
