    <RecordName>Transaction Information</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>The Type-1 record provides information describing the type and use or purpose for the transaction involved, a listing of each record included in the transaction, the originator or source of the physical record, and other useful and required information items. Record Type-1 is mandatory. Transmissions to be exchanged are required to contain one and only one Type-1 record per transaction. The Type-1 record shall always be the first record within the transaction and at least one more record shall be present in the file. The Type-2 record shall follow the Type-1 record.</RecordDescription>

    <RecordName>User-Defined Descriptive Text</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>The Type-2 record contains user-defined textual fields providing identification and descriptive information associated with the subject of the transaction. This record may include such information as the state or FBI numbers, physical characteristics, demographic data, and the subject's criminal history. Every transaction contains at least one Type-2 record; some transaction types may include more than 1 type-2 record.</RecordDescription>

    <RecordType>4</RecordType>
     <RecordName>High-resolution Grayscale Fingerprint Image</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>Type-4 records were designed to convey fingerprint images captured by an Automated Fingerprint Identification System (AFIS) live-scan reader, or other image capture devices operating at a nominal scanning resolution of 500 pixels per inch (ppi). Many systems still use this record type and it will remain an integral part of the ANSI-NIST standard. Many implementation domains and application profiles specify that unless fingers are missing or non-recordable, there shall be 14 Type-4 records in a file: ten rolled impressions of the individual fingers, two plain impressions of each thumb, and two simultaneously obtained plain impressions of the four remaining fingers on each hand. New users are encouraged to utilize record Type-14 to convey fingerprint images. Type-14 records may handle both 500 ppi images and those at greater resolutions that are now commonly exchanged.

All fields and data in Type-4 Record Types shall be recorded as binary information in traditional encoding with the content and order specified in the EBTS. Field 1.012: Nominal transmitting resolution (NTR) specifies the nominal transmitting resolution for fingerprint images transmitted in Type-4 or Type-7 records. For transactions that do not contain Type-3 through Type-7 fingerprint image records, this field shall be set to "00.00". A single transaction can only contain multiple Type-4 and/or Type-7 records if all images have the same resolution.</RecordDescription>

  <RecordDesc>
    <RecordType>7</RecordType>
    <RecordName>User-Defined Image</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>Type-7 records contain user-defined image information relating to the transaction submitted for processing. This record was intended as a temporary measure to enable the exchange of image data that would be defined by specific record types in later versions of the ANSI-NIST standard. Since some older systems still use this record type, NGI accepts it.

New implementations based on this standard are encouraged to use the Record Type-13: Friction-ridge Latent Image Record for latent records and other record types, as appropriate, for transmitting biometric and forensic images. Images transmitted using Record Type-7 shall consist of scanned pixels that may be either binary or grayscale output. Each grayscale pixel value shall be expressed as an unsigned byte. A value of 0 shall be used to define a black pixel and an unsigned value of 255 shall be used to define a white pixel. For binary pixels, a value of 0 shall represent a white pixel and a value of 1 shall represent a black pixel. 

For EBTS transactions, Field 1.012: Nominal transmitting resolution (NTR) specifies the nominal transmitting resolution for fingerprint images transmitted in Type-4 or Type-7 records. For Type-7 records, the transmitting resolution shall either be 495-505ppi (500+-1%) or 990-1010ppi (1000+- 1%). A single transaction can only contain multiple Type-4 and/or Type-7 records if all images have the same resolution.</RecordDescription>

    <RecordType>9</RecordType>
    <RecordName>Minutiae Data</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>Type-9 records shall contain text describing minutiae and related information encoded from a finger, palm, or plantar image. The Type-9 record shall also be used to exchange minutiae and related information from latent friction ridge images between similar or different systems. Each record shall represent the processed (automated and/or manual) image data from which the characteristics are stated. The primary use of this record type shall be for remote searching of latent prints. The number of Type-9 records for a latent search transaction depends on the Type of Transaction (TOT/1.004).

NGI will allow for both FBI IAFIS Feature Set and the ANSI/NIST Extended Feature Set (EFS). The Extended Feature Set allows the user to take advantage of the additional latent search capabilities (palm and supplemental searching, returning matched features, etc.) delivered with NGI Increment 3, and should be used for all new implementations of latent examination workstations that will interface with FBI/CJIS.  When both sets are present, NGI will use the Extended Feature Set. When features are being returned, NGI will place those features in the Extended Feature Set only.</RecordDescription>

    <RecordType>10</RecordType>
    <RecordName>Facial, Other Body Part, or Scar, Mark Tattoo (SMT) Image</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>Type-10 image records contain and are used to exchange image data from the face, scars, (needle) marks, and tattoos (SMT).    It can be used to exchange both grayscale and color image data in a compressed or uncompressed form.  Textual and analytic information pertinent to the digitized image is also contained in this record type. NGI accepts images as defined in ANSI/NIST-ITL.  

A submission may include several Type-10 images of a particular part of the body. For instance, a photograph of a tattoo may cover the entire tattoo. Another may be a zoom-in shot of a portion of the tattoo. In order to link these two images, the same index number is assigned to the field Type-10 Reference Number (10.039/T10). Note that these images would have different IDC values.</RecordDescription>

    <RecordType>13</RecordType>
    <RecordName>Variable-resolution Latent Friction-Ridge Image</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>Type-13 image records contain and are used to exchange variable-resolution latent friction ridge image data (fingerprint, palmprint and/or plantar) together with fixed and user-defined textual information fields pertinent to the digitized image. In all cases, NGI will use this record type to accept various latent, unsolved images at 1000 ppi from users for the purpose of investigative searching of different repositories. The variable resolution latent image data contained in the Type-13 record shall be uncompressed or may be the output from a lossless compression algorithm. The number of latent records in a transaction depends on the transaction type (TOT/1.004).</RecordDescription>

  <RecordDesc>
    <RecordType>14</RecordType>
    <RecordName>Variable-resolution Fingerprint Image</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>The Type-14 record contains and is used to exchange exemplar fingerprint image data, such as a rolled tenprint, an identification flat, or a complete friction ridge exemplar. All fingerprint impressions shall be acquired from a card, a single or multiple-finger flat-capture device, contactless fingerprint sensor that outputs 2D fingerprint images, or a live-scan device. Captured images may be transmitted to agencies that will automatically extract the desired feature information from the images for matching purposes. Textual information regarding the scanning resolution, the image size and other parameters or comments required to process the image are recorded as fields within the record. The Type-14 record is also used to exchange identification flats of multiple fingers (simultaneous plain impressions captured on a platen).

NGI has expanded the use of the Type-14 to include available images as described in the ANSI/NIST-ITL. These images consist of fingerprints (rolled and plain), supplemental palm prints and supplemental fingerprint images. The user-defined field Image Source (ISC/14.200) indicates to which image set the image being transmitted belongs.

Note: Tenprint images and supplemental finger images (exemplar lower joint and extreme tips) in Type-14 records within EBTS transactions shall be scanned at either 500ppi or 1000ppi.  When submitting supplemental fingerprints to NGI in the Type-14 record, an Entire Joint Image (EJI) image should contain at least the full FV1 or FV3 image along with the corresponding coordinates to be used in the verification process of the fingerprints submitted.</RecordDescription>

    <RecordType>15</RecordType>
    <RecordName>Variable-resolution Palmprint Image</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>Type-15 image records contain and are used to exchange palm print image data together with fixed and user-defined textual information fields pertinent to the digitized image. While the Type-15 record may be used for the exchange of 19.69 ppmm (500 ppi) images (all images shall be no less than 500 ppi), it is strongly recommended that the class resolution for Type-15 images be 39.37 ppmm (1000 ppi). Note that as the resolution is increased, more detailed ridge and structure information becomes available in the image. The variable-resolution palm print image data contained in the Type-15 record may be in a compressed form. 

NGI expanded the use of the Type-15 to include available palm print and supplemental fingerprint and palm print images as described in the ANSI/NIST-ITL. The user-defined field Image Source (ISC/15.200) indicates to which image set the image being transmitted belongs (e.g., is the image from the supplemental card or a palm print card).</RecordDescription>

    <RecordType>17</RecordType>
    <RecordName>Iris Image</RecordName><!--BioCTS Category:Editorial | Modified to match standard (May, 2017)-->
    <RecordDescription>Type-17 image records contain iris image data. This record type was developed to provide a basic level of interoperability and harmonization with the ANSI INCITS 379-2004 Iris Image Interchange Format and the ISO/IEC 19794-6 Iris Image Data Interchange Format.

A user can exchange generic iris image data using mandatory fields of this record type, and optional fields to exchange additional information available in the INCITS 379-2004 - Iris Image Interchange Format standard and the ISO/IEC 19794-6 Iris Image Data Interchange Format standard. Images may be monochrome or color with 256 or more intensity levels (gray or per-color component), and vary in size depending on field of view and compression. This record type specifies interchange formats for biometric authentication systems that utilize iris recognition. The formats all store sampled pixel data from rectilinear images. The data shall be encoded as a raw array of intensity values, a raw array of red green blue color values, or as losslessly compressed or lossy-compressed versions thereof. Two of the formats are specialized for small record sizes; these are achieved by cropping and masking the images to support efficient compression.</RecordDescription>
