Reader/card selection and information in Identity Manager

This describes how to find out all Integrated Circuit Card Serial Numbers (ICCSN) of all smartcards inserted into a card reader, or to have an overview of them, and read and return them into a field. The values will be separated by ',' (comma). If no token is found the action will fail.

1. Define like this in the encoding description:
   

   [Fields]
   ICCSNS_OF_ALL_TOKEN=
   ...
    
   [Description]
   RetrieveAllTokens=true
   AllTokensIccsnsField=ICCSNS_OF_ALL_TOKEN

   Description of the elements:
   

   Element	Description
   RetrieveAllTokens=true	Triggers to read all ICCSNs of inserted smartcards.
   AllTokensIccsnsField	Defines the field into which the ICCSNs of all smartcards are written.
   UseICCSNwithATR=true	Triggers to suffix the Answer To Reset (ATR) to the ICCSN, separated by a hyphen, like [ICCSN]-[ATR], for example, 2153000082960364-3BF99600008131FE45454F4E43617264563173

You can select the smartcard to be used for the defined applications of the encoding description via ICCSN.

1. Define like this in the encoding description:
   

   [Fields]
   ICCSN=
   ...
    
   [Description]
   UseSelectCriteriaIccsn=true
   SelectCriteriaIccsn=ICCSN
   UseICCSNwithATR=true

   Description of the elements:
   

   Element	Description
   UseSelectCriteriaIccsn=true	Triggers to use the ICCSN as the criteria for selecting a smartcard for this encoding description.
   SelectCriteriaIccsn	Defines to use the ICCSN of the related field that also has to be defined in the Fields section.
   UseICCSNwithATR=true	Expects  the Answer To Reset (ATR) to be suffixed to the ICCSN, separated by a hyphen, like [ICCSN]-[ATR], for example, 2153000082960364-3BF99600008131FE45454F4E43617264563173. This is done to uniquely identify a token, even so different models are used, and the ICCSN is only expected to be unique within the same model.

You can add the ICCSN of the used smartcard to the mapped fields, right after the encoding has finished.

1. Define like this in the encoding description:
   

   [Fields]
   ICCSN=
   ...
    
   [Description]
   IccsnField=ICCSN

   Description of the elements:
   

   Element	Description
   IccsnField	Defines the field into which the ICCSN of the used smartcard has to be written. If this definition is missing, no ICCSN will be returned. Note that the related field also has to be defined in the Fields section and have the Read attribute (see below).
   UseICCSNwithATR=true	Triggers to suffix the Answer To Reset (ATR) to the ICCSN, separated by a hyphen, like [ICCSN]-[ATR], for example, 2153000082960364-3BF99600008131FE45454F4E43617264563173

2. Set the Read attribute in the Encoding Fields tab to get the value into your datamap:
   

You can add the Answer To Reset (ATR) of the used smartcard to the mapped fields right after the encoding has finished.

1. Define like this in the encoding description:
   

   [Fields]
   ATR=
   ...
    
   [Description]
   AtrField=ATR

   Description of the elements:
   

   Element	Description
   AtrField	Defines the field into which the ATR of the used smartcard has to be written. If this definition is missing, no ATR will be returned. Note that the related field also has to be defined in the Fields section and have the Read attribute (see below).

2. Set the Read-attribute in the Encoding Fields tab to get the value into your datamap:
   

This functionality is supported for CardOS smartcards only.

You can read the values from the card and write them to the mapped fields.

1. Define like this in the encoding description:
   

   [Fields]
   OsVersion=
   (...)
   [Description]
   OsVersionField=OsVersion

   This encoding triggers to read the value from the card and return it in a mapped field named OsVersion.

2. In the configuration of the mapped fields, map it to a process variable and set the Read attribute (like in the examples for reading ICCSN / ATR above).

Return values:

If the command is successful, it will return two bytes as hex values representing the OS version in ATR coding. Otherwise it will return an empty string.

• Byte 1: OS Class (1st historical byte in Default ATR)
• Byte 2: OS Version (2nd historical byte in Default ATR)
• For CardOS V5.0: C901

This functionality is supported for CardOS smartcards only.

You can read the values from the card and write them to the mapped fields.

1. Define like this in the encoding description:

   [Fields]
   PackageInformation=
   (...)
   [Description]
   PackageInformationField=PackageInformation

   This encoding triggers to read the value from the card and return it in a mapped field named PackageInformation.

2. In the configuration of the mapped fields, map it to a process variable and set the Read attribute (like in the examples for reading ICCSN / ATR above).

Return values:

If the command is successful, it will return the package information in TLV encoding. If no package information is available or the command failed, it will return an empty string. If more than one package is loaded, these will be concatenated in the response.

Example with a single package:

• A String for a single package will look like this (spaces added for better readability):
  • E1 0B 53 06 03 04 13 01 C9 01 8F 01 00
  • Response (Tag: E1; Length: 0B)
  • Package Information (Tag: 53; Length: 06)
  • PID (Tag: here 03, represents the MID; Length 04; Value is the PID: 13 01 C9 01)
  • State (Tag: 8F; Length: 01; Value: 00)
• Summary: Manufacturer ID (MID): 03; Package ID (PID): 13 01 C9 01; State: 00

Example with multiple packages:

• A String for a single package will look like this (spaces added for better readability):
  • E1 0B 53 06 11 04 06 01 C9 03 8F 01 01E1 0B 53 06 11 04 09 01 C9 03 8F 01 01E1 0B 53 06 03 04 13 01 C9 03 8F 01 01
  • Each package starts with the tag "E1". Split at this package and proceed as in the example with a single package.

Notes

• MIDs: 01..3F used for Atos packages.
• States: 0 = disabled; 1 = enabled; 2 = terminated

To select a specific card when multiple cards are attached to the system, you have two options:

• provide the specific ICCSN or
• use a card selection popup.

The latter is described here. This will display the CN attributes of the first found user certificate available on the card (however, at the maximum of currently 100 characters to limit the popup width). 

1. Define like this in the encoding description:
   

   [Description]
   RetrieveTokenByUserSelection=true
   ...

   Description of the elements:
   

   Element	Description
   RetrieveTokenByUserSelection=true	Triggers to use a reader selection popup.

Features:

• The syntax of each option is: [PC/SC reader name] [CN of the first user certificate or the text "empty card"]
• An empty card is defined by having no user certificate, for example, a blank (not initialized) card, a just initialized card, ...
• Currently, a reader having a card without a user certificate but with just intermediate and root certificates will be also regarded as empty card.
• Contactless slots are also displayed.
• The read operations on the smartcard are limited for performance, that is, we stop reading as soon as we find the first user certificate.
• The displayed options are sorted by their reader names alphabetically.
• An option can have a maximum of currently 100 characters to limit the popup width. If longer, 97 character plus "..." will be displayed.
• If just one possible option could be found (for example, multiple readers available but only one card inserted) that option will automatically be selected (and logged) and the encoding further processed on it without displaying the reader selection popup.
• When having no cards inserted into one of the available readers in a system, an EndProcessException with a detailed message will be thrown: "No inserted cards could be found while searching all available reader slots!"
• Reader selection gets displayed before any optional PIN or PUK popups.
• When aborting the reader selection popup by clicking on the "cancel" button, an EndprocessException will be thrown and logged.

You can read the token info structure from the card as JSON.

1. Define like this in the encoding description:
   

   [Fields]
   TOKEN_INFO_OUTPUT=
   (...)
   [Description]
   TokenInfoJsonField=TOKEN_INFO_OUTPUT

   In the configuration of the mapped fields, map it to a process variable and set the Read attribute (like in the examples for reading ICCSN / ATR above).

}

Note that utcTime is empty unless the token is equipped with a clock.
Flag names are listed without the "CKF_"-prefix.

Return values for Idopte middleware:

  "manufacturerID":"Example Company",
  "model":"ChipDoc",
  "serialNumber":"2222000020014711",
