i have a client who uses ID cards with a special RF chip which

is being read by some RF equipment into into a third party system.

this system controls user logins, time, access, etc.

does PBL 2017 have a feature to accept entries from such equipment?

if yes, does a gide of some kind exist on this technology?

thanks all in advance.

Hi Sascha;

  Yes that should be possible. Passport Canada for example uses an RF API DLL provided by the reader vendor that scans your Passport and reads the information from the RF chip embedded in the document. My suggestion would be to contact the RF reader vendor and see what API's & access mechanisms that they provide.

Regards ... Chris

Hi,

Most technical equipment has some form of machine accessible interface. 20 years ago it would be a text file format, currently it may be a JSON or XML format used by a web-service.

Bottom line: PB will in most cases be able to access such API using standard PB functionality: Reading from data files, calling external function or a web-service returning JSON, XML; or some proprietary data format.

In rare occasions the communication protocol is complex and requires technical details hard to write in PowerScript. In such case there is often a DLL file that you can call as external functions. If no such luck, you may need to write some kind of facade in C# or C++ and then call that facade from PowerScript.

I know of a product written in PowerBuilder that interfaces with pretty much any kind of standard equipment you find on an industrial manufacturing floor using files, external functions, web-services, or some other kind of standard interface that PowerBuilder supports.

Hi,

En mi opinion el equipo emisor de radiofrecuencia  necesita de un equipo receptor de radiofrecuencia, es decir de una antena y esta antena contar con sotware para ser instalado en el dispositivo que "escucha", si tu hardware no cuenta con algun plugin(software) tal vez, solo tal vez ... entonces podrias leer directamente un puerto (Serial, usb, otro) .

Powerbuilder permite via PBNI utilizar rutinas hechas en C

 

Espero que esto te pueda ayudar.

 

Saludos !
