Adds to existing law to establish the Second Amendment Financial Privacy Act.

This legislation will prohibit credit card companies from assigning a unique merchant category code to firearms retailers that sell weapons and ammunition in Idaho. The tracking of this unique merchant category will allow unprecedented surveillance of the 2nd Amendment activity by the sharing of financial information between financial institutions and the government. There will still be allowances for financial institutions to disclose this protected financial information if authorization is provided or required by a lawful subpoena.
