Yes, you need the post ID so you could add a global $post to reference the post object so something like:

function buy_card_shortcode() {
    global $post;
    $card_details = get_field('card_id');

    $output = '<a class="buy-card-class" href="https://www.ebay.com/sch/i.html?_nkw='. $card_details .'">eBay</a>';
    return $output;
}
add_shortcode( 'buy_card', 'buy_card_shortcode' );

I did adjust your output as I think there was an error there around where the variable was referenced, as well.
