Transaction Cancellation

This section in the Troubleshooting page details the new transaction cancellation flow.

Transaction Communication Error

This section in the Troubleshooting page further describes the new callback and Websocket response.

New Features

Frictionless Payment Feature

This feature aims to simplify the customer identification for merchants during Polling and Delayed Auth. With a properly configured SDK and Terminal, it is possible to track all transactions done with a specific card. This will help merchants identify their customers and associate transactions to the appropriate account.

The Frictionless Payment feature is fully supported only on IDTech plugins for now.

Settings

This feature requires a few settings to work.

Terminal

  1. Set a Merchant Portfolio to the terminal.
  2. Make sure that the following settings are selected on the Merchant Portfolio:
    • Enable Token Uniqueness
    • Enable Token Auto Sharing
  3. Enable the Allow Internet setting of the terminal.

SDK

Enable Secure Token with Polling or Delayed Auth.

  • Android
  • Java
  • C#
  • Websocket

// Delayed auth with Secure Token
AndroidTerminal.getInstance().enableDelayedAuthWithSecureToken(BigDecimal.valueOf(10.0);

// Polling with Secure Token
AndroidTerminal.getInstance().enablePollingWithSecureToken(BigDecimal.valueOf(10.0));        



// Delayed auth with Secure Token
JavaTerminal.getInstance().enableDelayedAuthWithSecureToken(BigDecimal.valueOf(10.0);

// Polling with Secure Token
JavaTerminal.getInstance().enablePollingWithSecureToken(BigDecimal.valueOf(10.0));



// Delayed auth with Secure Token
Terminal.Instance.EnableDelayedAuthWithSecureToken(10.0m);

// Polling with Secure Token
Terminal.Instance.EnablePollingWithSecureToken(10.0m);



// Delayed auth with Secure Token
{
    "type": "REQ_SET_DELAYED_AUTH_WITH_SECURE_TOKEN_ENABLED",
    "data": {
    "enabled": true,
        "initialAmount": 10.0
    }
}

// Polling with Secure Token
{
    "type": "REQ_SET_POLLING_WITH_SECURE_TOKEN_ENABLED",
    "data": {
    "enabled": true,
        "initialAmount": 10.0
    }
}

Flow

When the above settings are enabled the following flow will take place for each transaction.

  1. A card is read using a payment device.
  2. A Secure Token is registered on the Gateway.
  3. The transaction is processed against the Secure Token.

If all the settings above are correctly configured then the server will always return the same Secure Token Merchant Reference for the same card details. This can be used to link or group transactions to the same customer.

Limitation

  • If one card is registered multiple times on the Gateway, the first registration will be returned. This can happen when an terminal is used to register cards before the option Enable Token Uniqueness is enabled.

Secure Token History

The Secure Token history lets you to retrieve the last transactions processed with a Secure Token. This could be done during a Secure Token Registration/Update, Polling/Delayed Auth with Secure Token, or Secure Token History Retrieval.

Availability

Request Plugin
Secure Token Registration IDTech, BBPos
Secure Token Update IDTech, BBPos
Secure Token History Retrieval IDTech
Polling IDTech
Delayed Auth IDTech

Enabling the Feature

To enable the feature, add the secureTokenHistory field to the initDevice request data and set its value to true.

  • Android
  • C#
  • ObjC
  • Java
  • Websocket

HashMap data = new HashMap<>();
data.put("secureTokenHistory", true);
AndroidTerminal.getInstance().initDevice(DeviceEnum.BBPOSDEVICE, DeviceConnectionType.BLUETOOTH,  data);  



Dictionary data = new Dictionary();
data["secureTokenHistory"] = true;
Terminal.Instance.InitDevice(DeviceEnum.IDTECH, DeviceConnectionType.USB,  data);



NSMutableDictionary *data = [[NSMutableDictionary alloc] init];
[data setObject:[NSNumber numberWithBool:YES] forKey:@"secureTokenHistory"];
[[WTPSTerminal singleton] initDevice:BBPOSDEVICE withConnectionType:BLUETOOTH withBluetoothAddress:nil withDeviceData:data];



HashMap data = new HashMap<>();
data.put("secureTokenHistory", true);
JavaTerminal.getInstance().initDevice(DeviceEnum.IDTECH, DeviceConnectionType.USB,  data);   



{
    "type": "REQ_INIT_DEVICE",
    "data": {
        "device": "IDTECH",
        "inputMethod": "INSERT",
        "connectionType": "USB",
        "emvType": "QUICK_CHIP",
        "secureTokenHistory": true
    }
}

Usage

After the Secure Token History feature is enabled, the history is added to the field history as a list of CoreTransactionSummary.

Secure Token Registration/Update/History Retrieval

When the Secure Token response callback, onSecureTokenResponse/OnSecureTokenResponse, is triggered or the Websocket message RES_ON_SECURE_TOKEN_RESPONSE is received for these actions, you could get the history from the Secure Token response object.

  • Android
  • C#
  • ObjC
  • Java
  • Websocket

public void onSecureTokenResponse(CoreSecureTokenResponse secureTokenResponse) {
    CoreSecureToken secureToken = secureTokenResponse.getCoreSecureToken();
    ArrayList secureTokenHistory = secureToken.getHistory();
}



public void OnSecureTokenResponse(CoreSecureTokenResponse response)
{
    CoreSecureToken secureToken = response.coreSecureToken;
    List history = secureToken.history;
}



-(void)onSecureTokenResponse: (CoreSecureTokenResponse*)secureTokenResponse {
    CoreSecureToken * secureToken = secureTokenResponse.coreSecureToken;
    NSMutableArray* secureTokenHistory = secureToken.history;
}



public void onSecureTokenResponse(CoreSecureTokenResponse secureTokenResponse) {
    CoreSecureToken secureToken = secureTokenResponse.getCoreSecureToken();
    ArrayList secureTokenHistory = secureToken.getHistory();
}



{
    "type": "RES_ON_SECURE_TOKEN_RESPONSE",
    "responseType": "RESPONSE_OK",
    "data": {
        "secureTokenResponse": {

            }
            ]
        }
        }
    }
}
Delayed Auth/Polling with Secure Token (only for IDTech plugin)

The history is returned on the callback onRequestSetAmount/OnRequestSetAmount and Websocket message RES_ON_REQUEST_SET_AMOUNT

  • C#
  • Java
  • Websocket

public void OnRequestSetAmount(CoreSale coreSale)
{
    CoreSecureToken secureToken = coreSale.coreSecureToken;
    List history = secureToken.history;
}



public void onRequestSetAmount(CoreSale coreSale) {
    CoreSecureToken secureToken = coreSale.getCoreSecureToken();
    ArrayList secureTokenHistory = secureToken.getHistory();
}

IDTech Card Removal Timeouts

During Quick Chip transactions, you are prompted for card removal up to two times.

  1. After the card data has been read by the device
  2. When the card is left inserted on the first case up until the online sale response is retrieved

Setting the Timeouts

In this release, we added the support to specify the prompt timeout for each cases.

To configure the timeout for the first case, pass the field quickChipCardRemovalTimeoutInMillis with a value in milliseconds.

For the second case, use the field postTransactionCardRemovalTimeoutInMillis.

Minimum: 1000ms
Maximum: 255000ms

  • C#
  • Java
  • Websocket

Dictionary data = new Dictionary();
data["quickChipCardRemovalTimeoutInMillis"] = 30000;
data["postTransactionCardRemovalTimeoutInMillis"] = 30000;
Terminal.Instance.InitDevice(DeviceEnum.IDTECH, DeviceConnectionType.USB,  data);



HashMap data = new HashMap<>();
data.put("quickChipCardRemovalTimeoutInMillis", 30000);
data.put("postTransactionCardRemovalTimeoutInMillis", 30000);
JavaTerminal.getInstance().initDevice(DeviceEnum.IDTECH, DeviceConnectionType.USB,  data);   



{
    "type": "REQ_INIT_DEVICE",

    }
}

IDTech MiniSmart II APDU Command Exchange

The MiniSmart II device is capable of exchanging APDU commands with a smartcard but performing such feature requires direct calls to the IDTech library.

On the websocket solution, this is achievable through the device passthrough call messages.

Device Passthrough Request

{
  "type": "REQ_DEVICE_PASSTHRU",
  "data": {
    "methodName": "method_to_call",
    "parameters": {
            "someParamName": "someValue"
    }
  }
}

Device Passthrough Response

{
  "type": "RES_ON_DEVICE_PASSTHRU_RESPONSE",
  "responseType": "RESPONSE_OK",
  "data": {
        "someResponseDataName": "someValue"
  }
}

Performing the APDU Command Exchange

To perform the APDU command exchange, please see the steps below.

  1. Make sure the device is connected and initialized.

  2. Set the card type option to ISO (”00”).

    Request

     {
           "type": "REQ_DEVICE_PASSTHRU",
           "data": {
             "methodName": "setCardTypeOption",
             "parameters": {
               "cardType": "00"
             }
           }
         }

    Response

     {
           "type": "RES_ON_DEVICE_PASSTHRU_RESPONSE",
           "responseType": "RESPONSE_OK",
           "data": {
             "responseCodeString": "no error, beginning task.",
             "responseData": "06",
             "responseCode": 0
           }
         }

  3. Insert a card into the device.

  4. Send a device passthrough call message to power on the reader.
