Credit-Card-Terminals

This Java Library Communicate With Vx520

If you want to try how that library work please, follow this link: https://github.com/hadialbadaoui/Vx520-JAVA-Interface.git to download a simple application, help you to communicate with Vx520.

Note: Don't forget to download all 3 libraries:

• jssc-2.8.0.jar
• org.json.jar
• Credit_Card_Terminals.jar

And the 3 classes too, You can found it in the link below:

• Settlement
• Transaction
• Status

Tutorial:

1- Create a reference from class "Manage". Example: Manage MR = new Manage(); Manage Class contains these Attributes: - boolean status: return true or false. - String "errormessage": return an error message when the status was false. - Status statuslog: return all status happens in Vx520. - boolean settlementfound: return true when Vx520 return a settlement response. - Settlement settlement: Class has all attribute of settlement response. - boolean transactionfound: return true when Vx520 return a transaction response. - Transaction transaction: Class has all attribute of transaction response.

2- Create a reference from class "AreebaPOS". Example: AreebaPOS apos = new AreebaPOS(COM); COM is a string variable containing the name of the serial port. Example: "COM1"

Now you can create a reference from class "AreebaPOS" without parameter: the library will return the name of COM connected to serial port of Vx520.

3- We have three methods to use:

• SendTestToPOS: to test the connectivity of Vx520.

• SendTransactionToPOS(String TypeRequest, String Reference, String Amount, String Currency): Send a transaction to Vx520:

   . TypeRequest: "Sale", "Refund" and "Void".
   
   . Reference: Should be 8 digits.
   
   . Amount: Should be 12 digits.
   
   . Currency: Should be ($/USD) or (LL/LBP).
  

  This function return a class Manage.

• SendSettlementToPOS: This function return a class Manage.

Thank you, best regards.
