The bottom line: this pack is for anyone who needs a reliable set of tokens to test or provision systems that explicitly use EM4200 Wiegand format readers. It is not a universal key fob set, but for environments running Rosslare, Uhpote, Biostar and other EM technology readers the 50-pack offers a convenient way to deploy or test access without buying individual custom-encoded tags.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e26 Bit EM4200 Wiegand Format:\u003c\/strong\u003e Ensures the fobs are encoded to the EM standard that works with dedicated EM readers, reducing guesswork during system setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack of 50:\u003c\/strong\u003e Provides enough units for small sites, test deployments or staging areas so installers can test many doors or users at once.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Blue Design:\u003c\/strong\u003e The 30mm x 37mm x 5mm size and blue housing make the fobs easy to handle, carry on a keyring, and visually distinct in an access control environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyless Entry Convenience:\u003c\/strong\u003e Eliminates the need for cards in temporary or demo setups, offering instant proximity-based access for authorized personnel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks with EM Readers Only:\u003c\/strong\u003e Clear format limitation helps avoid wasted time trying to pair these with incompatible technologies.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe 50-pack is best for security technicians, installers, and small facilities that already run EM technology readers such as Rosslare, Uhpote or Biostar. It is especially useful as a test pack when configuring multiple readers or demonstrating system behavior to customers, since having many identical-format tokens simplifies commissioning.\u003c\/p\u003e\u003cp\u003eThose who should look elsewhere include anyone using non-EM readers (for example MIFARE, HID iCLASS or other proprietary formats) because these fobs will not communicate with those systems. Also, if you require custom encoding or serialized management through a specific vendor service, a generic test pack may not meet that need.\u003c\/p\u003e\u003ch2\u003ePros \u0026amp; Cons\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGood value for testing or short-term deployment with 50 identical EM-format fobs.\u003c\/li\u003e\n\u003cli\u003eCompact and durable blue fob size fits standard keyrings and is easy to store.\u003c\/li\u003e\n\u003cli\u003eStraightforward compatibility with common EM4200 Wiegand readers reduces setup friction for supported systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCons\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eLimited to EM technology readers only, so they will not work with non-EM card systems.\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003ePanopticon Tech\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e50 pcs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFormat\u003c\/td\u003e\n\u003ctd\u003e26 Bit EM4200 Wiegand\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Readers\u003c\/td\u003e\n\u003ctd\u003eEM technology readers (Rosslare, Uhpote, Biostar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAppearance\u003c\/td\u003e\n\u003ctd\u003eBlue fob, 30mm x 37mm x 5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUse Case\u003c\/td\u003e\n\u003ctd\u003eKeyless entry test pack \/ access control deployment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eOur Verdict\u003c\/h2\u003e\u003cp\u003eThe 50 pcs 26 Bit EM Blue Proximity Key Fobs are a practical, cost-effective test pack for technicians and small sites running EM4200 Wiegand readers.
