Using 13.56 MHz contactless smart card technology, the iCLASS� RK40 provides a powerful solution. Combine a contactless card presentation with a personal identification number (PIN) to support dual authentication of identity. Or, configure the panel for single-factor authentication, using only a card or a PIN. The PIN can be verified either at the access control panel or locally by the keypad reader. When verified locally, the PIN must be programmed into the iCLASS card. Featuring crisp architectural styling, the keypad reader has an elegantly curved faceplate. The 12-position weatherproof keypad uses discrete switches to provide positive tactile response, optionally reinforced by an audible tone. The keypad also features a waterproof silicone rubber boot, vandal-resistant metal keycaps, and backlit numbering. Environmental Certification: � RoHS, WEEE Environmentally Friendly: � Yes
