Right now it's only available in USD. Golden Card in other currencies is definitely on the product roadmap.
Hello Wagecan,
just wanted to let you know that I'm getting this error while accessing your site on Firefox:
An error occurred during a connection to wagecan.com. Invalid OCSP signing certificate in OCSP response. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT
Works fine with Chrome, though.
