Frequently Asked Questions

Q: What iButton and RFID formats does the TMRF-2RW programmer support?

A: The TMRF-2RW iButton Programmer reads DS1990A-F5, TM1990A-F5, DS1990R-F5 iButton tokens as well as TK4100 RFID key tags. For writing, it supports RW1990 iButton chips and T5577 125KHz RFID key tags, making it one of the most versatile 125KHz duplicators available.

Q: Do I need special software to use the TMRF-2RW RFID duplicator?

A: The TMRF-2RW is designed as a plug-and-play device. It connects via USB and is ready to use out of the box with no complex software installation required, making it accessible for both professionals and beginners.

Q: What is the difference between the read and write functions on this RFID copier?

A: The read function allows the TMRF-2RW to scan and capture the data stored on a source iButton token (DS1990A) or RFID key tag (TK4100). The write function then programs that captured data onto a compatible blank or rewritable chip — specifically RW1990 iButton tokens or T5577 RFID key tags — effectively creating a functional duplicate.

Q: Is the TMRF-2RW compatible with standard 125KHz access control systems?

A: Yes. The TMRF-2RW operates on the 125KHz frequency, which is the standard frequency used by a wide range of residential and commercial access control systems. As long as your system uses DS1990A iButton tokens or compatible 125KHz RFID key tags, this programmer is designed to work with it.
