Self service terminal development process

One 、 Common terminal product types （ Most products are developed or derived from the banking industry ）：

1、 Self service ATM （ Common industries ： Bank ）

2、 Card issuing machine （ Common industries ： Bank 、 The hospital 、 signal communication 、 Radio and television 、 Gas and other large enterprises ）

3、 Receipt cabinet （ Common industries ： Bank 、 Logistics Express ）

4、 Queuing machine （ Common industries ： Bank 、 The hospital 、 signal communication 、 Radio and television 、 Gas and other large enterprises ）

5、VTM（ Virtual counter ）（ Common industries ： Bank ）

 

Two 、 Self service terminal hardware selection

1、 Self development ： Terminal appearance design 、 Terminal structure design 、 Selection of embedded modules used by the terminal （ Such as ：ATM Deposit and withdrawal movement 、IC Card reader / Hairpin 、 ID card reader 、 tickertape / Pipelined printer 、 Laser printer 、 QR code scanner 、 camera 、 Fingerprint instrument 、 Card printer 、 Metal password keyboard, etc ......）

2、 Not self-developed ： Find a terminal manufacturer , It is enough to purchase the terminal products that meet the demand , Now the terminals on the market are basically the same , If you add a custom module or modify it slightly .

 

3、 ... and 、 Software development architecture selection

1、B/S framework ： adopt web The application program calls the mode of local hardware plug-in to realize the function of self-service terminal

Common technology ：web service、JS、ActiveX/ATL、 Firefox Google plugin （NPAPI/PPAPI）、HTTP、WebSocket

advantage ： Fast development speed 、 Product update is convenient 、 Interface design and call are convenient

shortcoming ：Web Calling the hardware module depends on the browser , Browser settings are complex 、 Browser compatibility issues 、 The response speed is a little slow 、 Poor stability of operating environment, etc ..

2、C/S framework ： The self-service terminal function is realized by directly calling the driver hardware through the application program

Common technology ：C#、VB、VC、delphi、QT、Socket、HTTP

advantage ： Easy to call hardware devices 、 Fast interface interaction response 、 The operating environment is stable

shortcoming ： Development is slow 、UI Design and call are troublesome 、 Product update is troublesome

3、CB/S framework ：C/S Schema inline B/S Architecture to implement automatic terminal functions

combination B/S、C/S The advantages and disadvantages of the architecture realize the system framework .

Four 、 Automatic terminal hardware calls common industry driven framework protocols

WOSA/XFS Protocol specification     Is in Windows A set of standard interfaces developed on the basis of open system architecture

opos Protocol specification       For application developers to be independent of , The retail peripherals they visit

5、 ... and 、 Automatic terminal hardware module introduction

Such as ：ATM Movement
