Dear all,

I am the new starter of the contactless smartcard research. As I know it has Type A or B RF modulation from the card reader to the card. Could anyone introduce to me that which company sales the Type B smartcard development kits?

Moreover, my boss asked me to measure the amplitude of the recevied signal in the smartcard at different distance from the card reader. Could anyone recommend some materials about this? I am really need to your help. :''(

Thanks
wccheng
