When a compatible passive tag (Keyfob or Card) is brought within its range (up to 10cm), the tag is energized and transmits its 12-digit unique ID back to the module. The EM18 then formats this data and sends it out as a serial string.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eWhy it’s a Security Essential:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Simple Serial Communication: The module communicates using standard TTL Serial at 9600 baud. This means you can read RFID data using just a single wire (TX) connected to any microcontroller's RX pin, without needing specialized RFID libraries.\u003cbr\u003e• Integrated Antenna: The antenna is already tuned and embedded within the module's casing. This eliminates the risk of signal interference or detuning that often occurs with external \"wire-coil\" antennas.\u003cbr\u003e• Visual and Audio Indicators: The module features dedicated pins to drive an LED and a Buzzer. When a card is successfully read, the module can automatically trigger these indicators to provide instant user feedback.\u003cbr\u003e• Robust Reading Distance: Depending on the size of the tag, the EM18 can achieve a read distance of up to 10cm, which is superior to many smaller 13.56MHz systems.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eTechnical Capabilities:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Operating Frequency: 125 kHz (LF).\u003cbr\u003e• Supply Voltage: 5V DC (Required for stable operation and maximum read range).\u003cbr\u003e• Data Format: 10-digit ASCII ID + 2-digit Checksum.\u003cbr\u003e• Read Range: 5cm – 10cm.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003eThe EM18 is the primary choice for industrial attendance systems, automatic gate openers, inventory check-out stations, and secure equipment lockers.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46405621645511,"sku":"TE-RFIDEM-115","price":439.77,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/EM18RFIDTTLmodule.png?v=1776443909","url":"https:\/\/shop.tinkedge.tech\/products\/em18-rfid-ttl-module","provider":"TinkEdge","version":"1.0","type":"link"}
