The code is in C# Console.WriteLine("Send Message Echo..."); ManageConnection.ManageSocket _manage = new ManageConnection.ManageSocket(IpAmex, PortAmex); TupleList<Encoding, string> _request = new TupleList<Encoding, string>(); _request.Add(Encoding.GetEncoding(500), "1804"); _request.Add(Encoding.UTF8, "2030018000000000"); _request.Add(Encoding.GetEncoding(500), "000000"); _request

My question is based on ISO8583 Transaction message standard. My problem statement is to develop an app which will decode the ISO8583 message which is provided as a input in HEX format. for ex : my input = 0200B2200000001000000000000000800000201234000000010000011072218012345606A5DFGR021ABCDEFGHIJ 1234567890 Using jPOS library i am parsing this hex code and output is as follows : MTI : 0200 Field-3 : 201234 Field-4 : 000000010000 Field-7 : 0110722180 Field-11 : 123456 Field-44 : A5DFGR Field-105 : ABCDEFGHIJ 1234567890 Now this parsed output i want to decode i.e i want to convert it into the

In ISO message, what's the use of stan and rrn fields ? Also who will generate the these values while sending ISO messages? STAN - usually generated by your network interface to make it unique per online message request. RRN - is the transaction related reference and can be generated by POS system, Integrator environment or the generation can be done behind the authorisation interface by the acquired/issuer systems. Depending of RRN generation side the responsibility to make it unique (or keep same for some cases) can be at the client side or at the authorisation institutions side. Both values
