It communicates via the Dallas 1-Wire protocol and is compatible with most TM card and iButton readers worldwide.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this iButton key need a battery?\u003c\/h4\u003e\n\u003cp\u003eA: No — the TM1990A-F5 iButton requires no external power or battery. It draws the small amount of power it needs directly from the collector\/reader when touched to the contact point, making it completely maintenance-free.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the TM1990 iButton waterproof and durable?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The key features a 304 stainless steel shell with high-temperature resistant resin sealing, making it 100% watertight. It has also been tested for vibration resistance, electrical reliability, and extreme temperature performance — ensuring it holds up through years of daily use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How is the TM1990 different from a standard RFID card?\u003c\/h4\u003e\n\u003cp\u003eA: Unlike flat plastic RFID cards, the TM1990 iButton uses a Dallas 1-Wire touch-contact interface housed in a rugged stainless steel disc. It carries a globally unique 64-bit serial number (family code 01) that cannot be duplicated by standard RFID devices, offering a distinct and reliable identification method for compatible access control systems.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the TM1990 DS1990 iButton Touch Memory Key used for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The TM1990 \/ DS1990 iButton Touch Memory Key is a compact RFID copy card used in access control and security systems including electronic door locks, security patrol check-in stations, sauna and cabinet locks, and intercom entry systems.
