MRTD

Overview

The parser supports all versions of Machine Readable Travel Documents (MRTD) specified by the International Civil Aviation Organization (ICAO).

The ICAO specifies four types of MRTDs:

TD1 (id cards)
TD2 (other official travel documents)
TD3/MRP (passports)
MRV (A & B) (visas)

In addition, the parser supports the following non-ICAO standards:

SwissDL (Swiss driving license)
TD2/FrenchID (French identity card)

Regex patterns

Use the following regex pattern to filter out MRTD codes:

Type	Regex
TD1 Regex Pattern	([A-Z0-9<]{30}\n?){3}
TD2 Regex Pattern	([A-Z0-9<]{36}\n?){2}
TD2 French Regex Pattern	Same as TD2 Regex Pattern
TD3 Regex Pattern	([A-Z0-9<]{44}\n?){2}
MRV_A Regex Pattern	Same as TD2 Regex Pattern
MRV_B Regex Pattern	Same as TD3 Regex Pattern
Swiss Driving License Regex Pattern	[A-Z0-9<]{9}\n([A-Z0-9<]{30}\n?){2}

Common fields

The four types of MRTDs specified by the ICAO share most of the fields encoded in the Machine Readable Zone (MRZ) of the travel document.

The following fields are exposed for all ICAO MRTDs:

Data Element ID	Meaning	Parsed Content
documentType	Document Type	One of the following values: ‘td1’ ‘td2’ ‘td3/mrp’ ‘mrv’
documentCode	Document Type Code	One of the following values: ‘P[passport type id]’ - indicates a passport, ‘ID’ - indicates an id card, ‘CA’ - indicates a Canada permanent resident card
documentNumber	Document Number / Passport Number	String with the following interpretation: TD1 & TD2: uniquely identifies the document from all other MRTDs issued by the State or organization. TD3/MRP: Passport number MRV: Either the passport number or the visa number, at the discretion of the issuing State.
expiryDate	Date of expiry	Dictionary with these key/value pairs: ‘year’ : YY, ‘month’: MM, ‘day’ : DD with YY, MM, DD as integers. Entries are omitted from the dictionary if they are not specified by the input.
issuingState	Issuing State	Three-letter string specified in ICAO document 9303-3.
name	Name	Dictionary with these key/value pairs: ‘primary’: [primary identifiers, e.g., surname] ‘secondary’: [secondary identifiers, e.g., given name or titles] ‘truncated’: boolean, indicates whether primary or secondary identifiers are truncated
birthDate	Date of birth	Dictionary with these key/value pairs: ‘year’ : YY, ‘month’: MM, ‘day’ : DD with YY, MM, DD as integers. Entries are omitted from the dictionary if they are not specified by the input.
sex	Sex	One of the following values: ‘female’ ‘male’ ‘nonspecified’
nationality	Nationality	Three-letter string specified in ICAO document 9303-3.

Please refer to the following sections for deviations from the the above table.

TD3 fields

‘optional’: Usually employed to store the document holder’s personal number.

MRV fields

‘documentNumber’: At the discretion of the issuing State, either the passport number or the visa number shall be used in this field.
‘expiryDate’: In most cases this will be the date of expiry of the MRV and indicates the last day on which the visa can be used to seek entry. For some States this will be the date by or on which the holder should have left.

MRTD extensions

The French ID format is different then other ICAO formats in Common and does not contain all information described in the common fields section. For clarity, there is a complete example of TD2/FrenchID format.

Parser Options

The parser can be configured by providing a JSON string containing key / value pairs. The following configuration options are available:

Key	Value Type	Description
relaxedChecksumValidation	Boolean	Enabling this option prevents the parser from failing for invalid checksums. Checksum verification results for the parsed fields are indicated using the ‘metadata’ field.
allowFalsePositiveCompensation	Boolean	When enabled the parser compensates characters that were recognized incorrectly by the OCR. Should not be used together with relaxedChecksumValidation option. By default set to false.

Metadata

The metadata field provides more information about the parsing of the input’s fields. The dictionary encoded in the JSON string of the ‘parsed’ field contains the following entries:

Key

Value Type

Description

checksumValidation

Dictionary

This dictionary contains a key / value entry for every check digit in the input document with the following properties:

key: Name of the field associated with the check digit.
value: Boolean indicating the success status of the checksum verification.
