Elatec’s TWN4 Family allows users to read and write to almost any 125kHz/134.2kHz and 13.56MHz tags and/or
labels. It supports all major transponders from various suppliers like ATMEL, EM, ST, MIFARE NXP, TI, HID, LEGIC,
etc. and ISO standards like ISO14443A/B including layer 4 (T=CL), ISO15693, ISO18092 / ECMA-340 (NFC).
The new generation is a direct enhancement to the successful TWN3 family as it comes in the same mechanical
dimensions (OEM PCB and Desktop Housing). Desktop supports host communication via USB or RS232.
Special Features:
Powerful SDK for writing Apps which are executed directly on the reader
Infield Upgradeable
Direct chip-commands support
Two onboard SAM sockets (Secure Access Module)
CCID and PC/SC 2.011)
Additional interfaces for OEM PCB version
Serial (logical level 3.3V, CMOS 5V tolerant), I²C, SPI2), Clock/Data3), Wiegand3), CAN2)3),1-Wire2)
 Dedicated expansion bus for connection of LCD, mass storage, etc.
 2 GPIOs
