On the proximity side, the K-KPR uses proven RFID technology and is HID (125 kHz) compatible supporting most HID 125 kHz credentials. On the keypad side, soft blue backlighting and a continuously illuminated 5 key make the keypad much more visible for night-time use. And the face plate has a tactile design with raised numerals and a 'pip' on the 5 key to assist the visually-impaired as well. With dual proximity and PIN verification, the K-KPR offers higher security for those applications that require an extra layer of protection. The K-KPR's electronics are protected in an epoxy potting so it's suitable for indoor or outdoor use.
