GO2NFC141U NFC Reader
Mode: G141U
Overview
The GO2NFC141U NFC Reader is contactless smart card reader/writer developed based on the 13.56 MHz
Contactless (RFID) Technology. Unlike other NFC readers/writers, GO2NFC141U is very compact and
small.
GO2NFC141U is a plug-and-play USB device. It is compatible with different devices and applications.
Compliant with the ISO/IEC18092 standard for Near Field Communication (NFC), it supports not only Mifare
and ISO 14443 A and B cards but also all four types of NFC tags. It also could pushes or pulls data with
Android NFC phone. Although in a small size, the proximity operating distance of GO2NFC141U is 5 cm.
With an access speed of up to 424 kbps and a full USB speed of up to 12 Mbps, GO2NFC141U can also
read and write quickly and efficiently, depending on the type of contactless tag in use.
Software for GO2NFC141U is available for both Windows OS and Linux. Most important, the software is
open source, totally free for any changing and usage. The software contains operation function such as
reading/writing card, pushing URL to Android phone, pulling message from Android phone.
The GO2NFC141U NFC Reader is ideal for access control, e-payment, e-ticketing for events and mass
transit, toll road fare collection and network authentication.
