The TWN4 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 (T=CL ), ISO14443B (T=CL), ISO15693, 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 fifty 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.
