The KR300's dual-frequency design future-proofs your installation — you can use existing 125KHz proximity cards alongside newer 13.56MHz NFC\/MIFARE smart cards without replacing hardware. The epoxy-potted, IP65-rated enclosure ensures the reader stands up to outdoor exposure, car wash environments, and demanding industrial settings. With standard Wiegand output, the KR300 integrates seamlessly with virtually every major access control panel on the market.\u003c\/p\u003e\n\n\u003cp\u003eFor more information on physical access control security standards, visit the \u003ca href=\"https:\/\/www.nist.gov\/topics\/identity-access-management\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eNIST Identity \u0026amp; Access Management resource page\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What types of cards are compatible with the KR300 RFID card reader?\u003c\/h4\u003e\n\u003cp\u003eA: The KR300 supports two card technologies simultaneously: 125KHz proximity\/EM\/ID cards and 13.56MHz IC\/NFC cards including MIFARE Classic 1K (S50). This dual-frequency capability means it works with a wide range of existing access cards and modern NFC-enabled credentials.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the KR300 suitable for outdoor installation?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The KR300 carries an IP65 waterproof rating, meaning it is fully protected against dust ingress and low-pressure water jets from any direction. Its solid epoxy-potted construction and operating temperature range of -10°C to +70°C make it well-suited for outdoor gates, building entrances, and other exposed locations.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What Wiegand output formats does the KR300 support?\u003c\/h4\u003e\n\u003cp\u003eA: The KR300 outputs 26-bit Wiegand when reading 125KHz proximity cards and 34\/36-bit Wiegand when reading 13.56MHz IC\/NFC cards. Both formats are industry-standard and compatible with the vast majority of access control panels and controllers available today.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I connect the external LED and buzzer to the KR300?\u003c\/h4\u003e\n\u003cp\u003eA: The KR300 provides two dedicated input ports — one for external LED control and one for external buzzer control. These ports allow your access control panel to drive the LED indicator and audible beeper on the reader, giving users clear visual and audio feedback upon card presentation.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What types of cards are compatible with the KR300 RFID card reader?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The KR300 supports two card technologies simultaneously: 125KHz proximity\/EM\/ID cards and 13.56MHz IC\/NFC cards including MIFARE Classic 1K (S50).
