NIST補助指紋カードデータ（SFCD）は指紋認識データで、522人の5520枚の指紋画像を含み、画像解像度は832x768で、米国標準技術研究院（NIST）によって公開されています。NIST補助指紋カードデータデータベースは、NIST特殊データベース9において比較的大きな指紋パターンサンプルを提供しており、これらのサンプルの自然発生頻度と遷移指紋カテゴリの発生頻度はどちらも低いです。NIST特殊データベース10のデータは3つのディスクセットで、最初のCD - ROMには2160枚の画像が含まれ、最後の2枚のCD - ROMには1680枚の画像が含まれています。分割された各画像は832 x 768ピクセルで、FBIが提供する国家犯罪情報センター（NCIC）の分類を使用して分類されています。このデータベースは、指紋サンプルを使って指紋システムを評価する上で貴重なツールであり、より多くの自然発生頻度の低いカテゴリと遷移NCIC分類を提供します。
