SBSDKNFCPassportReader


@interface SBSDKNFCPassportReader : NSObject

A class to extract the data from a passport’s Near Field Communication (NFC) chip.

Notes:

Requires

Requires iOS 13.0+

Your app needs to add the “Near Field Communication Tag Reading” entitlement
Your apps info.plist needs to define the passport nfc application ID. To do so add the following entry: “com.apple.developer.nfc.readersession.iso7816.select-identifiers” and as the first element add the passport application ID “A0000002471001”

                    -initWithPassportNumber:birthDate:expirationDate:initialMessage:delegate:

Designated initializer.

Declaration

Objective-C

- (nonnull instancetype)
    initWithPassportNumber:(nonnull NSString *)passportNumber
                 birthDate:(nonnull NSDate *)birthDate
            expirationDate:(nonnull NSDate *)expirationDate
            initialMessage:(nullable NSString *)messsage
                  delegate:(nonnull id<SBSDKPassportReaderDelegate>)delegate;

Swift

init(passportNumber: String, birthDate: Date, expirationDate: Date, initialMessage messsage: String?, delegate: SBSDKPassportReaderDelegate)

Parameters

`passportNumber`	The passports alphanumerical ID, as printed on the passport.
`birthDate`	The passport holders birth date.
`expirationDate`	The passports expiry date
`messsage`	The initial message being shown on the NFC-scanning UI when NFC reading starts.
`delegate`	The delegate of the passport reader.

Return Value

A newly initialized and ready to use instance of SBSDKNFCPassportReader.


                    
                    
                    -setMessage:

Sets the message being displayed on the NFC-scanning UI.

Note: Repeated message changes may not be reflected in the UI due to the asynchronous updating. This is a restriction of the underlying Apple API.

Declaration

Objective-C

- (void)setMessage:(nonnull NSString *)message;

Swift

func setMessage(_ message: String)

Parameters


                                message

The message to be displayed.


                    
                    
                    -enumerateDatagroups:

Enumerates all available data group types on the passports NFC chip and returns them to the completion handler.

Note: Not all available data groups are accessible/readable with the basic authentication that we are allowed to use. Most often only DG1 and DG2 are accessible.

Declaration

Objective-C

- (void)enumerateDatagroups:
    (nonnull void (^)(NSArray<SBSDKNFCDatagroupType *> *_Nonnull))completion;

Swift

func enumerateDatagroups(_ completion: @escaping ([String]) -> Void)

Parameters


                                completion

The completion handler called when the operation has finished. Passes an array of available data group types.


                    
                    
                    -downloadDatagroupsOfType:shouldIgnoreUnavailableGroups:completion:

Downloads and parses the specified data groups.

Declaration

Objective-C

- (void)downloadDatagroupsOfType:
            (nonnull NSArray<SBSDKNFCDatagroupType *> *)types
    shouldIgnoreUnavailableGroups:(BOOL)shouldIgnoreUnavailableGroups
                       completion:(nonnull void (^)(NSArray<SBSDKNFCDatagroup *>
                                                        *_Nonnull))completion;

Swift

func downloadDatagroups(ofType types: [String], shouldIgnoreUnavailableGroups: Bool, completion: @escaping ([SBSDKNFCDatagroup]) -> Void)

Parameters

`types`	An array of data group types the receiver should read and parse. Usually this is only DG1 and DG2.
`shouldIgnoreUnavailableGroups`	If set to NO, then the state when some of requested groups will be missing or unavailable will be treated as an error state and nothing will return. If set to YES, the method will just return available groups, ignoring unavailable.
`completion`	The completion handler that is called when reading and parsing of the specified data groups has finished. The completion handler is called passing an array of readily parsed data group objects.


                    
                    
                    -downloadDatagroupsOfType:completion:

Downloads and parses the specified data groups. Unavailable data groups are ignored.

Declaration

Objective-C

- (void)
    downloadDatagroupsOfType:(nonnull NSArray<SBSDKNFCDatagroupType *> *)types
                  completion:
                      (nonnull void (^)(NSArray<SBSDKNFCDatagroup *> *_Nonnull))
                          completion;

Swift

func downloadDatagroups(ofType types: [String], completion: @escaping ([SBSDKNFCDatagroup]) -> Void)

Parameters

`types`	An array of data group types the receiver should read and parse. Usually this is only DG1 and DG2.
`completion`	The completion handler that is called when reading and parsing of the specified data groups has finished. The completion handler is called passing an array of readily parsed data group objects.
