myNFC is a framework allowing JavaScript developers to create cross-platform mobile & NFC applications for smart phones and other embedded systems. These NOT web based applications can be loaded dynamically and can offer a wide user experience.
This project provides a chip card interface device driver for the PC/SC Lite server deamon (pcscd). The driver provides a standard PC/SC interface to NFC devices supported by libnfc.
Note, that this project is currently not actively developed. However, the code has been adopted by the libnfc-Team. See https://code.google.com/p/ifdnfc/source/checkout.
NFC is a scalable, distributed chat server and client implemented in Java. Notable features include built in load balancing and HTTP-tunneling support. Using the load balancing, a distributed network of servers can be formed, similar to an IRC network.
