Choosing the reader

Most users have only a single smart card reader connected to the system at a time. Some people have several readers visible on the PC/SC layer: an embedded 3G/4G modem which exposes its SIM slot as a reader, always connected Yubikey, virtual readers created by SDK-s, or an embedded reader in a laptop that is not suitable for some operations. GlobalPlatformPro allows to fine tune the default reader via environment variables.

$GP_READER

If you know that you would always want to use a specific reader with GPPro, specify the name of it in $GP_READER. It will always be chosen if available.

$ export GP_READER="ACS ACR122U PICC Interface"

$GP_READER_IGNORE

To always ignore certain readers with GPPro, specify fragments of their names in $GP_READER_IGNORE, separated by semicolon.

$ export GP_READER_IGNORE="Yubikey;Alcor"
