Optional reader modules may support 13.56MHz cards as well — please confirm with us at time of order.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can the SCR100 operate without being connected to a PC or network?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The SCR100 supports fully standalone operation. It stores up to 30,000 users and 50,000 transaction records onboard. Log data can be exported offline using a USB pen drive, making it ideal for locations without continuous network access.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the Wiegand In \u0026amp; Out function work on this controller?\u003c\/h4\u003e\n\u003cp\u003eA: The Wiegand In port allows you to connect an additional external card reader (for example, an outdoor reader) to the SCR100 controller. The Wiegand Out port lets the SCR100 itself act as an external reader for a separate access control panel, giving you flexible multi-reader and multi-door configuration options.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What software is needed to manage the SCR100 remotely?\u003c\/h4\u003e\n\u003cp\u003eA: The SCR100 includes an embedded web server, so basic configuration and monitoring can be done from any web browser on the same network — no additional software required. For advanced time-attendance reporting and multi-device management, it is also compatible with third-party access control management software via Ethernet or RS232\/RS485.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What type of RFID cards are compatible with the SCR100 access controller?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The SCR100 uses a built-in 125kHz EM proximity reader, making it compatible with standard 125kHz EM format RFID cards and key fobs.
