System Messaging / Emulation

For make Connection between Host application and atm application, a system mesagging needed for each other can communicate on same behavior. Here is most system messaging used on automated teller machine.

• NDC
NDC or NCR Direct Connect is messaging from NCR (national cash register). One of famous ATM manufacturing. NDC have many version and the last version is added more feature from back version. In NDC have two mode, first is NDC Native mode ,and the other is NDC 912 mode to accommodate ATM-C/HOST with DDC Protocol.

• DDC 911/912
Same As like NDC, DDC or Diebold Direct Connect create by Diebold.inc the most player in ATM industries. There a 2 type, DDC 911 and 912. for 911 commonly using on America continent. 912. if we compare between NDC and DDC, DDC have one point plus. In a atm can use multiple currency, but according my opinion, its to hard and too complicated for status and error message. Not like NDC give more information about status and error in simple way.

• ISO 8583
ISO 8583 is standard international for Financial Transaction System. Some ATM using this protocol for communicate with the Host./ATM Controller. Another machine using this protocol is EDC (electronic data capture).

• Properity
This protocol is tailored made, and customized depend the host and the bank.
