ATM (std) Client Interface Using Jpos

[kapilashantha rajapaksha]

Dear Sir,

I'm looking for a develop an interface which is going to use ATM transactions. And later on planing to connect ATMs to our existing Switch (Currently supported interfaces are  POS terminals ,Internet bank, IPG  ).  In fact, I'm a newer to ATM based transactions and its behaviour,messages ,protocol etc.. but I hope that I can integrate this.  Before that I have few clarification regarding JPOS appi

1. Is it supported for message format of ATMs?

2. We are using standard ATM client application, so Is it using ISO8583 message ? or will it depend on the ATM brand ? since I never see message example

3. What is NDC/NDC+/DCC?   is it kind of message structure like ISO8583 ? or will it only use for ATM controlling such as (updating ATM client app via remote , etc ..)

4. If it's using for transactions, then can jpos create the NDC/DCC messages like ISOmsg creation?

5. Is there any example (raw data ) to analyse ATM request for whatever message ?

6. What is the best connection mode between ATM and Switch?  example persistent  or non-persistent

Much appreciate your expert on this

Regards

You can define ATM messages as fsdmsg's using a schema to interpret the protocol, assumption, messages are not iso8583 formatted.

ATM's have their custom protocols, newer atms tend to support iso8583 messages and their proprietary message formats.

NDC/NDC+ are NCR proprietary formats, DDC is Diebold proprietary format. Most atms try to emulate NCR/Diebold formats as they are the most used protocols

Yes they can, used fsdmsg or iso8583 messages to unpack requests and pack responses.

Raw data will!l probably not be available, use the spec to create them or go the route of using ATM emulators (these are pretty  expensive).

These can be persistent and ATM can be a client or server and they can be configured to support a 2byte message length pretended to the message.
If you are dealing with dial up arms then there will probably be a box in between that does the dial up to tcp conversion. If its dialup the chances are you connections won't be persistent, dials in, sends request, receives response and disconnects.

The document for  message specification DDC, is it freely available ?  and If so, where can it be downloaded ? Further what is the best and recommended (according to your experience )  simulator if it's ordering by us ?

Not very likely, but which ATM vendor/protocol do you need? I would
speak to your possibly, future ATM providers to check what they do and
not not support and provide in the way of documentation.

Sorry yes it's DCC for diebold proprietary format.  At this stage, I'm looking for communicating with both NDC+ and DCC. Much thanks if you show right direction me since.

ATM protocol manuals are not freely available but they do come along with the ATMs , so you can most likely get to them through the entity that owns them to write the driver for.

Emulators are a good bet for convenience as testing with real atms can be impractical as you would need access to a  test atm.

I have used Paragons atm emulator in the past and would vouch for it , got really good support on it, although  now its a part part of ACI and as all ACI things, chances are it will be very expensive.

Lexcel is another one that comes to mind, for which I have no hands on experience.

Thanks and I try with Paragons :) but pretty expensive

ATMulator Plus NDC is USD$25,000 to USD$35,000 excluding any withholding tax.  The range is because of whether you need RKL, EMV, Cash deposit functionality as add-on feature into ATMulator Plus NDC.

I need Raw ATM data for exchanged mesages but as you said that its probably not be available. Where can i get / buy ATM emulators?

Why not google it?

I have done so and have not found one that i can actualy use to test my jpos server. All the ones i found are just school projects that are not good enough.

[willard kurisa]

Found it thanks

paragon and lexcel come to mind. Not cheap at all :)
