Use Verifone Barcode scanner over MFi


To run the example project, clone the repo, and run pod install from the Example directory first.



  1. Add pod 'AdyenBarcoder' to your Podfile.
  2. Run pod install.


  1. Add github "adyen/adyen-barcoder-ios" to your Cartfile.
  2. Run carthage update.
  3. Link the framework with your target as described in Carthage Readme.


Copy files from AdyenBarcoder folder.


You need to add com.verifone.pmr.barcode in the Supported external accessory protocols into Info.plist file


To initialize Barcoder library simply get the shared instance and set your BarcoderDelegate.

let barcoder = Barcoder.sharedInstance
barcoder.delegate = self


The only mandatory method is didScan(barcode:). This is where the result of the scan will be delivered. You can also receive state updates on didChange(status:).

@objc public protocol BarcoderDelegate {
    @objc func didScan(barcode: Barcode)
    @objc optional func didChange(status: BarcoderStatus)
    @objc optional func didReceiveLog(message: String)


Barcoder library supports four modes:

@objc public enum BarcoderMode: Int {
    case hardwareAndSofwareButton // Default mode. Both hardware button and software commands (startSoftScan, stopSoftScan) are enabled.
    case hardwareButton // Only hardware button is enabled. Calls to software commands will be ignored.
    case softwareButton // Only software commands are enabled. Clicking the hardware button will not trigger the lights.
    case disabled // Disabled.

You can set the mode via the mode variable on Barcoder.sharedInstance. The default value is .hardwareAndSofwareButton.


For starting a soft scan:


To stop the soft scan:


Important: Remember to allways call stopSoftScan after starting a startSoftScan.


There are five log levels available: None, Error, Info, Debug, Trace. To set the log level simply set the variable on your Barcoder instance:

barcoder.logLevel = .debug

You will receive each new log message via BarcoderDelegate method didReceiveLog(message:).

Advanced Usage

Interleaved 2 of 5

You can enable or disable setting the interleaved2of5 variable on Barcoder instance:

barcoder.interleaved2Of5 = true

Custom Symbology

It's possible to customize the barcoder symbology with setSymbology(enabled:) method:

//Should be called AFTER .ready event on `didChange(status:)`
barcoder.setSymbology(.EN_CODE11, enabled: true)

The full list of accepted symbology can be found on SymPid enum.

Example usage in Objective-C

    // Do not forget to put in Podfile:
    // use_frameworks!
    // pod "AdyenBarcoder"
    // And put in Info.plist file:
    // "com.verifone.pmr.barcode" in the "Supported external accessory protocols"

#import <AdyenBarcoder/AdyenBarcoder-Swift.h>

@interface ViewController () <BarcoderDelegate>

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Initialize
    [Barcoder sharedInstance].delegate = self;

// Did scanned
- (void)didScanWithBarcode:(Barcode * _Nonnull)barcode {
    NSLog(@"Scanned barcode: %@", barcode.text);
