CardScan (Bouncer SDK) module

VGS Collect SDK provides CardScan integration module for collecting and setting scanned card data into VGSTextFields.
It's required to use scan module provided by VGS, which is audited by VGS PCI requirements.

Pricing

VGS Collect CardScan module is a paid integration with Bouncer. VGS customers pay Bouncer for the functionality and receive a 20% discount off of Bouncer's normal pricing: $0.12 per card scan. For VGS customers expecting to scan >40,000 cards per month, customers can contact Bouncer directly for an attractive best-available custom plan supported by the VGS-Bouncer partnership.

Before you start

You should obtain API Key for CardScan commercial usage, generating it on the Bouncer admin console.

Integration

Integrate with Cocoapods

To use CardScan with VGSCollectSDK you should add CardScan module alongside with core VGSCollectSDK module into your App Podfile:

pod 'VGSCollectSDK'
pod 'VGSCollectSDK/CardScan'

Integrate with Carthage

Carthage users should point to VGSCollectSDK repository and use next generated frameworks: VGSCollectSDK, VGSCardScanCollector, and CardScan.

Make the following entry in your Cartfile:

Note
 At this time, Carthage does not provide a way to build only specific repository submodules. All submodules and their dependencies will be built with the above command. However, you don't need to copy frameworks you aren't using in your project. For using CardScan with VGSCollectSDK copy VGSCollectSDK, VGSCardScanCollector, and CardScan from the Carthage Build directory after carthage update completes. Other submodules can safely be deleted.
Important
 • Don't forget to add NSCameraUsageDescription key with the camera usage description into your App Info.plist.

CradScanDataType

CradScanDataType is an Enum of supported scan data types by CardScan module.

CradIODataTypeType, Value
.cardNumberString, 16 digits number
.expirationDateString, "mm/yy" digits
.expirationMonthString, "mm" digits
.expirationYearString, "yy" digits
.nameString, characters

Usage

Create UI Form with VGSTextfields, if not done yet.
Inside your ViewController create and configure VGSCardScanController instance:

class ViewController: UIViewController {

    // Create VGSCardScanController instance
    var scanController = VGSCardScanController(apiKey: "YOUR_CARD_SCAN_API_KEY")

    // Scan card button
    var scanButton = UIButton()

    /// Initialize VGSCollect instance
    var vgsCollect = VGSCollect(id: "<VAULT_ID>", environment: .sandbox)

    /// VGS UI Elements
    var cardNumberField = VGSCardTextField()
    var cardHolderNameField = VGSTextField()
    var expCardDateField = VGSTextField()
    var cvcField = VGSTextField()


    override func viewDidLoad() {
       super.viewDidLoad()

       /// Set and implement VGSCardScanDelegate to handle user interaction with CardScan
       scanController.delegate = self

       /// Add action to handle scan button touch
       scanButton.addTarget(self, action: #selector(scanData(_:)), for: .touchUpInside)

       /// Setup Fields Layout and Configuration
       ...
    }

     // Present scan ViewController
     @objc func scanData(_ sender: UIButton) {
        /// Check if CardScan can run on current device
        if VGSCardScanController.isCompatible() {
          scanController.presentCardScanner(on: self, animated: true, completion: nil)
        } else {
          print("This device not compatible with CardScan")
        }

Implement VGSCardScanControllerDelegate methods.
To setup scanned data into specific VGSTextFields implement textFieldForScannedData:. If scanned data is valid it will be set in your VGSTextFields automatically after user confirmation. Check CradScanDataType to get available scanned data types.

extension ViewController: VGSCardScanControllerDelegate {

  //When scanning finished on CardScan screen
  func userDidFinishScan() {
      scanController.dismissCardScanner(animated: true, completion: {
          // add actions on scan controller dismiss completion
      })
  }

  //When user press Back button on CardScan screen
  func userDidCancelScan() {
      scanController.dismissCardScanner(animated: true, completion: nil)
  }

  //Asks VGSTextField where scanned data with type need to be set.
  func textFieldForScannedData(type: CradIODataType) -> VGSTextField? {
      switch type {
      case .expirationDate:

      case .name:
