TWN4 MultiTech

The TWN4 MultiTech family of transponder readers and writers allows users to read and write to almost any 125 kHz / 134.2 kHz and 13.56 MHz tags and/or labels.

Elatec’s TWN4 MultiTech is a contactless RFID reader/writer and a direct enhancement of the TWN3 with the same mechanical dimensions (OEM PCB and Desktop Housing).

TWN4 MultiTech also supports all major transponders from various suppliers like ATMEL, EM, ST, NXP, TI, HID, LEGIC, and ISO standards like ISO14443A/B (T=CL), ISO15692 and ISO18092/ECMA-340 (NFC).

About the MultiTech Family

TWN4 MultiTechAbout the MultiTech Family

Elatec’s TWN4 MultiTech is a contactless RFID reader/writer and a direct enhancement of the TWN3 with the same mechanical dimensions (OEM PCB and Desktop Housing). The TWN4 MultiTech family of transponder readers and writers allows users to read and write to almost any 125 kHz / 134.2 kHz and 13.56 MHz tags and/or labels. TWN4 MultiTech also supports all major transponders from various suppliers like ATMEL, EM, ST, NXP, TI, HID, LEGIC, and ISO standards like ISO14443A/B (T=CL), ISO15692 and ISO18092/ECMA-340 (NFC).


Key features of the TWN4 MultiTech include a powerful SDK for writing Apps which are executed directly on the reader, infield upgradeable firmware, direct chip-commands support, and additional interfaces for the OEM PCB version. TWN4 MultiTech simultaneously reads more than sixty RFID technologies from both the low frequency (LF) and high frequency (HF) bands, including NFC. This provides the option to select as many of the technologies required instead of being forced to select just a few like most other readers.

In addition, TWN4 MultiTech can also be used as a diagnostic tool by installing the card analyzer application called TechTracer. It now becomes capable of identifying the card type, data length, and unique identification number. This eliminates the requirement to physically send cards off-site for identification while potentially saving weeks of waiting for the diagnosis. Analyzing the card in front of the end customer demonstrates that the card can be read, which is normally a requirement of a proof-of-concept.
