NFC Scan - Integration & Usage Guide

Prerequisites

• IncdOnboarding variant including "-nfc", eg. version "5.33.0-s-nfc".

Integration

• Turn on Near Field Communication Tag Reading under the Capabilities tab for the project’s target. This step:

  • Adds the NFC tag-reading feature to the App ID.
  • Adds the Near Field Communication Tag Reader Session Formats Entitlement to the entitlements file.

• Add the NFCReaderUsageDescription key as a string item to the Info.plist file. For the value, enter a string that describes the reason the app needs access to the device’s NFC reader. If the app attempts to read a tag without providing this key and string, the app will crash.

• Add interface for interacting with an ISO 7816 tag to App's Info.plist:

<key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key>
  <array>
    <string>A0000002471001</string>
    <string>A0000002472001</string>
    <string>00000000000000</string>
  </array>

• If integrating through Cocoapods then no further actions are required.
• If manually integrating: Add OpenSSL.xcframework to your project (should be Embedded & signed). In build settings for key LD_RUNPATH_SEARCH_PATHS add path @executable_path/Frameworks.

Usage

To add NFC Scan module to the flow, simply:

1. Add it to a IncdOnboardingFlowConfiguration:

  flowConfig.addNfcScan(showNFCSymbolConfirmationScreen: true/false, processNFCData: true/false)

2. Add callback to your IncdOnboardingDelegate:

  func onNFCScanCompleted(_ result: NFCScanResult) { 
    // process result
  }

Parameters for addNfcScan():

• showNFCSymbolConfirmationScreen: Show Is NFC Available screen. Default is true.
• showInitialDataConfirmationScreen: Show edit OCR screen at beginning of module. Default is true.
• processNFCData: A Boolean value that indicates whether to process NFC data on backend or not. Default is true.

Returning result of the module is a 'NFCScanResult' struct which contains:

• facePhoto: A face photo extracted from NFC chip.
• dg1: DG1 data extracted from NFC chip.
• error: An NFC Scan error. nil means there were no errors.

Possible values for NFCScanError:

• error(_ error: IncdError): The associated value contains the specific IncdError case.
• notAvailable: NFC scan is not available.
• userDocumentHasNoChip: User selected NO for NFC chip availability.
• noScanAttemptsRemaining: User has used all NFC scan attempts without success.
