Introduction

Mobile Point‐of‐Sales (mPOS) systems that process sensitive payment information are required to certify their payment applications to the Payment Application Data Security Standard (PA‐DSS). The addition of EMV certification and continued need for both encryption and tokenization has become a concern for both merchants and integrators. Instituting and maintaining these standards requires significant financial and employee resources in order to adhere to the Payments Card Industry Data Security Standards (PCI DSS) compliance requirements. Subsequently, any changes made in the mPOS system, may require a partial or full recertification, which increases the cost and time to market. BridgePay has engaged these issues through our product line, the Pay Guardian suite, to better serve the needs of our integrators and merchants.

PayGuardian iOS is a light weight, highly secure iOS framework library that integrates seamlessly into mPOS applications. PayGuardian iOS facilitates the transaction process by handling the collection and transmission of sensitive payment information as an out of scope PA-DSS solution, thereby offloading the certification responsibility from merchants and integrators. PayGuardian iOS is EMV enabled, handles point to point encryption, and tokenizes all transactions to ensure transaction
processing is seamless and secure.

The mPOS application collects transaction data such as the dollar amount, invoice number, tender type, transaction type, merchant account information, etc…

The mPOS application constructs a BPNPaymentRequest object and passes it to a new instance of the PayGuardianTransaction object.
PayGuardian obtains the card information via the claiming of the mPOS device using the Bluetooth API (re: Ingenico RBA SDK) and validates the transaction request object.

The mPOS device prompts to swipe or insert the card and transmits the card information to the PayGuardian application, which captures the card data as a swiped or EMV transaction respectively.

PayGuardian constructs the payload request and transmits the transaction request to the Payment Gateway.

PayGuardian transmits the transaction response returned from the Payment Gateway back to the mPOS application.

The mPOS application implementation responds accordingly to the transaction response.

info.plist Configuration

You must add a ‘Privacy - Bluetooth Always Usage Description’ to this file in order to enable the permissions checker to handle obtaining permission.

Device Configuration

ID TECH

VP3300 (formerly Unipay III) 

The VP3300 is a Bluetooth Low Energy device that can be paired by passing in a known friendly name into the TerminalCommConfig object or else having the controller scan for and return all unpaired devices in range. When pairing, the friendly name is used only to identify the device to the CoreBluetooth manager. The NSUUID that is generated represents the connection between the host device and the reader and should be stored in your application. This NSUUID is not transferrable to other devices.

Note on bleFriendlyName: the documented behavior of this device is that it will first search for a device matching the friendly name if provided but will connect to the first unpaired device in range if it is not found. For this reason we suggest passing in an empty string or nil.

Device Registration

The example below sets up a transaction object for scanning nearby unpaired VP3300 devices. Once the device is done scanning, it returns an array of device friendly names which can then be used to pair the desired reader. The friendly name gets passed into the transaction object via connectWithFriendlyName; a successful connection will return the UUID representing the pairing between that device and reader.

- (void) scanForDevices { _transaction = [[PayGuardianTransaction alloc] initAndScanForDevices: TERMINAL_TYPE_IDTECH_UNIPAY_BT onReaderStateChanged: ^(PayGuardianReaderState readerState) { dispatch_async(dispatch_get_main_queue(), ^(void){ switch(readerState) { case Connected: // Store the UUID so registration does not need to occur again unless // unpairing occurs. self->_registeredUUID = [self->_transaction getConnectedDeviceIdentifier]; [self appendToLogMessages:[NSString stringWithFormat:@"%@", self->_registeredUUID]]; [self->_prefs setObject:[NSString stringWithFormat:@"%@", self->_registeredUUID] forKey:UUID_KEY]; break; case ScanComplete: self->_foundBleNames = self->_transaction.getFoundDeviceNames; if (self->_foundBleNames != nil && self->_foundBleNames.count > 0) { for (NSString* name in self->_foundBleNames) { [self appendToLogMessages:[NSString stringWithFormat:@"Found %@", name]]; } [self presentAvailableDevicesPicker]; } else { [self appendToLogMessages:@"No devices located"]; } break; default: break; } }); }]; } - (void) presentAvailableDevicesPicker { UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Available devices" message:@"" preferredStyle:UIAlertControllerStyleActionSheet]; for (NSString* name in _foundBleNames) { UIAlertAction* a = [UIAlertAction actionWithTitle:name style:UIAlertActionStyleDefault handler:^(UIAlertAction* action) { [self->_transaction connectWithFriendlyName:name]; }]; [alert addAction:a]; } // This is needed to anchor the popover on iPad implementations UIPopoverPresentationController *popPresenter = [alert popoverPresentationController]; popPresenter.sourceView = __logMessages; popPresenter.sourceRect = __logMessages.bounds; [self presentViewController:alert animated:YES completion:^(){ self->_foundBleNames = nil; }]; }
Device Registration - legacy

This block is an example of using the pre-iOS 9 BLE scanning method. Using this method will generate a First Responder error on any project that uses a SceneDelegate and should not be used for new development.

- (void) vp3300Registration { _transaction = [[PayGuardianTransaction alloc] initForRegistration:TERMINAL_TYPE_IDTECH_UNIPAY_BT bleFriendlyName:@"" onReaderStateChanged:^(PayGuardianReaderState readerState) { dispatch_async(dispatch_get_main_queue(), ^(void){ switch(readerState) { case Connected: NSLog(@"Card reader status is connected"); NSLog(@"%@", [[_transaction getConnectedDeviceIdentifier] UUIDString]); [[self bleUUID] setText:[[_transaction getConnectedDeviceIdentifier] UUIDString]]; break; default: } }];

[transaction resumeCardRead]; }];

Integration Process

Getting Started

The PayGuardian iOS Framework files must be added to the XCode project prior to the start of an integration.

Contact: A test or live merchant account with BridgePay is necessary to successfully process transactions. To acquire a test account and receive the developer application build of the PayGuardian iOS Framework library, complete the Test Account Request form.

Transaction Flow Summary

The following list summarizes the steps involved in processing a transaction:

  1. The mPOS system collects order information and determines that the customer will pay with one of the supported tender types.

  2. The mPOS system invokes the PayGuardian iOS Framework library.

  3. The payment screen loads and prompts the user to enter customer and payment data.

  4. After collecting all transaction information, PayGuardian transmits the data to the server.

  5. After receiving a response from the host, the payment screen returns the processing results back to the mPOS system.

  6. The mPOS system analyses response data.

EMV Transaction Support

EMV Implementation Details

PayGuardian also supports EMV transactions. Upon receiving the transaction request, PayGuardian calls the device to obtain the card information. The device will prompt to Swipe or Insert the Card. Upon the card insertion or card swipe, the transaction will be processed according to the user selection.

Minimum Requirement:
Card Reader Version: 23.02 RBA
When a transaction is being processed as an EMV transaction, the communication messages between the Card Reader device and the PayGuardian Application are uniquely identified by a “33.” message identifier. There are currently seven message types used during EMV transactions. The message type is selected using a subcommand identifier which is embedded in the message. Subcommand identifiers are used to identify the different message types:

  1. EMV Transaction Initiation Message

    1. The '00.' EMV Transaction Initiation message is sent from the PayGuardian to the device to indicate the type of transaction purchase.

  2. EMV Track 2 Equivalent Data Message

    1. The '02.' EMV Track 2 Equivalent Data message is sent from the device to the PayGuardian. This data is similar to the Track 2 data which is stored on a magnetic stripe card.

  3. EMV Authorization Request Message

    1. The '03.' EMV Authorization Request message is sent from the device to the PayGuardian to provide the cryptographic  information necessary to authorize the transaction.  The authorization process is initiated by the device issuing a request to the PayGuardian.

  4. EMV Authorization Response Message

    1. The '04.' EMV Authorization Response message is sent from the PayGuardian to the device in response to the EMV Authorization Request message. This message includes cryptographic information which is read by the embedded microchip on the card.

EMV Purchase Transaction Flow

This section describes the message flow for EMV transactions once PayGuardian receives the transaction request from the mPOS application.

  • PayGuardian will activate the Device based on the terminal type specified in the transaction payment request.

  • The card number, expiration date, and cardholder name will be transmitted in the transaction request through the Device (Ingenico terminals will prompt for amount
    confirmation).

  • The transaction response will be returned to PayGuardian and to the Device. If the Device has a signature capture pad, the customer will be prompted to Sign and Accept on the Device.

  • If the electronic signature is captured, it will be returned encoded in the response object.

  • Remove the EMV card from the Device.

Additional Feature Information

HealthCare Support

PayGuardian also provides support for healthcare industry transactions (FSA or HSA accounts) through use of the Extended Data fields. The additional healthcare specific fields and associated amounts will need to be specified only when the required healthCareData (see page 11) element is populated with a value other than ‘nil’ (indicates that healthcare data will be present as part of the transaction request). The only required parameter value within the healthCareData element is healthCareAmt; all other healthcare specific parameters are optional. If medical transportation was included as a value, then the transitAmt parameter should be added.

Depending on the type of service rendered, additional amounts can be specified to healthCareAmt to indicate how much was spent on prescription, vision, dental, and clinic/hospitalization services. The total of prescription, vision, dental and clinic amounts can be less than or equal to healthCareAmt.
