How Would I Build an RFID Interface?
Is there a standardized way of creating one?
I assume you are asking how you would build a link between a radio frequency identification reader and a back-end system, and that would depend on the type of RFID system you deploy. Passive ultrahigh-frequency (UHF) readers based on the second-generation Electronic Product Code (EPC) air-interface protocol often employ a GS1 standard called the low-level reader protocol (LLRP), which specifies the interface between readers and applications. If you are using an EPC system, follow LLRP.
Most other systems do not have a standardized way of creating an interface. Different interrogators output data in different formats—XML or plain text, for example. You will need to build a custom interface that imports this information, formats it and then shares it with back-end systems in a useable format. If you are not utilizing an EPC solution, I suggest that you consult with the company that manufactures the readers you are using.
