ok … foi no link ai , li o que tinha lá ( falando sobre um tal de RFID Anywhere , que pelo o que eu intendi , é um software ou bibliotecas , não sei direito … ) baixei o exemplo que tem lá … mas quando vou compilar não roda …
diz lá no site que não precisa ter nenhum hardware pra rodar o programa … mas mesmo assim não rodou …
as classes são :
