The FDMSBenefit component is used to authorize Electronic Benefits Transfer (EBT) transactions with the FDMS system on the North platform. An EBT transaction is similar to a Debit transaction, using a PIN and KSN, but is used for Food Stamp or Cash Benefit programs. This component allows for simple, direct, secure communication to the First Data platform through a standard Internet connection.
This component connects to the First Data Merchant Services (FDMS) processor, by way of the Datawire VXN transaction transport network. Transactions originating with these components go through Datawire, to the FDMS processor where the transaction is authorized. The result is then returned back through Datawire and received by the component. This component can be integrated into web pages or stand-alone Point Of Sale applications. Because all SSL communications are handled inside the component, any application or web page can be deployed without the need for expensive dedicated SSL servers.
An EBT Card (also known as Cash Benefit Card or Food Stamps) works similar to a bank debit card. EBT is a special application of electronic funds transfer (EFT), or debit card technology, which takes money directly from one account and transfers it to another (credit cards, by comparison, simply record a sale for payment later). The steps to setting up the component and sending transactions are outlined below: First, you must register and activate your account with Datawire. Datawire will provide you with a MerchantNumber and MerchantTerminalNumber, but you'll need to use the FDMSRegister component to activate the merchant and receive a DatawireId. Once you acquire the DatawireId and receive your transaction URLs through Service Discovery, you may begin to authorize transactions.
To authorize a credit card, set the MerchantNumber and MerchantTerminalNumber with the values supplied by FDMS and Datawire, and the DatawireId with the value retrieved by the FDMSRegister component after activating your merchant account. Set the URL property with one of the URLs you retrieved during Service Discovery.
FDMSBenefit.MerchantNumber = "000000999990"; //Supplied by FDMS/Datawire FDMSBenefit.MerchantTerminalNumber = "555555"; //Supplied by FDMS/Datawire FDMSBenefit.DatawireId = "0000B47FFFFFFFFFFFFF"; //Retrieved with the FDMSRegister component. FDMSBenefit.URL = "https://staging1.datawire.net/sd/"; //Retrieved with the FDMSRegister component.Next, set properties that contain details about the transaction. The TransactionNumber should be incremented for every transaction you send. The TransactionAmount must be set, and it should contain the amount to be charged, with an implied decimal point (ie: $1.00 is "100"). Like the FDMSDebit component, there is no IndustryType property for FDMSBenefit.The format of the transmitted data does not change for different industry types. Do note that the FDMSBenefit component can only be used in a retail (or restaurant, grocery store, etc) environment, where the card and customer are present. The card must be swiped and track2 data must be specified in the MagneticStripe field. Cash Benefit transactions may never be manually-keyed, but Food Stamp transactions may be. EBT transactions also require the customer to input his or her PIN into a certified PIN Pad device, which will return an encrypted PIN and a Key Sequence Number to the merchant. These must be submitted with the transaction in the EncryptedPIN and KSN properties. A unique ReceiptNumber number used to identify the transaction on the merchant's system is also required for all transactions. This number must also be printed on the customer's receipt.
EBT transactions differ from credit card authorizations in that they are real-time -- Funds are immediately removed from (or added to) the customer's cash benefit or food stamp account. However, even though EBT transactions are real-time, FDMS requires they be settled at the end of the day just like credit card transactions.
The following transaction set is available for the Cash Benefit BenefitType:
|Sale with or without CashBack||A simple sale transaction. The customer may request CashBack.|
|CashWithdrawal||The customer makes no purchase, but instead withdraws funds directly from his or her cash benefit account.|
|BalanceInquiry||Retrieves all balances available on the EBT card.|
|ReverseLastTransaction||Sends a "Timeout Reversal" transaction. This is used when the merchant does not receive a response to the Sale or CashWithdrawal, and ensures that the EBT card will not be charged twice if the merchant then makes a subsequent transaction.|
|Sale without CashBack||A simple sale transaction. The customer may NOT receive CashBack.|
|Credit||Returns funds to the customer's EBT card.|
|BalanceInquiry||Retrieves all balances available on the EBT card.|
|ReverseLastTransaction||Sends a "Timeout Reversal" transaction. This is used when the merchant does not receive a response to the Credit or Sale, and ensures that the EBT card will not be charged twice if the merchant then makes a subsequent transaction.|
Note that only food stamp transactions may be voice-authorized, attempting to send a VoucherAuthCode or VoucherNumber in a Sale transaction when the BenefitType is set to Cash Benefits will result in an error.
The example below shows how to submit a simple food stamp sale transaction.
FDMSBenefit.TransactionNumber = 1; FDMSBenefit.TransactionAmount = "2500"; FDMSBenefit.Card.MagneticStripe = "5076800000001355=120412000000000123"; FDMSBenefit.Card.EntryDataSource = edsTrack2; FDMSBenefit.EncryptedPIN = "7B8491A1007E82B0"; FDMSBenefit.KSN = "876543210900300000C"; FDMSBenefit.ReceiptNumber = "123456"; FDMSBenefit1.BenefitType = btFoodStamps; FDMSBenefit.Sale();
When the component receives a response, the result of the authorization will be available in several Response properties. The DatawireStatus and DatawireReturnCode indicate whether any errors occurred while passing the transaction through the Datawire VXN system. These two properties alone do not indicate a successful transaction, they only tell whether or not there were any problems transporting the authorization request and response through the Datawire system. If the transaction was successfully authorized by FDMS, then the CaptureFlag will be True, and the ApprovalCode will contain an approval code that beings with "AP". (or "AL" for components that support partially-approved/split-tender transactions). The remaining response properties provide additional information about the transaction, including cash benefit and food stamp account balances (for supported cards).
Once an authorization request is approved, the money in the customer's account is blocked and tagged for the merchant. This transaction must go through the Batch Settlement process in order for the blocked money to be transferred to the merchant account. This is done by passing the XML aggregate returned from the GetDetailAggregate method to the FDMSSettle component. Usually, a Batch Settlement of all authorized transactions is done at the end of each business day.
Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).
