first he did ping test to check connection.

and he read our document(W3150A+/W5100 Errata Sheet) to check his code.

Unlike other web control UCCs, what was interesting was that used RFID reader.

Relay can controled by each card, and when tag unregistered card, then serial monitor shows "unknown key!"

This project has good resource and lot of user can refer it
