Re: How can I know how many logical channels does my card support?

Is your said "supplementary logical channel"? You can use 'MANAGE CHANNEL' command to open and close supplementary logical channels, and the Basic Logical Channel(channel number zero) can never be closed. The details of 'MANAGE CHANNEL' command you can refer to Global Platform Specification.
