Proximity cards and PHPRunner

What is proximity card and how can it interact with PHP applications?

Major hardware manufacturers usually provide SDK (software development kit) in popular programming languages. Make sure your

In the past for a PHPR project we had with RFID Card Readers, I wrote a Windows program, running as a service, that connected to the device (OmniKey we used) and read each RFID transmitting data to the keyboard buffer, with a special character for start and stop. Then I had a javascript event in the project that intercepted the input, and filtered out start and stop chars (if found meaning key events coming from my deamon) and cleared out the RFID tag.
I've done something similar with Barcode scanners for an inventory picking PHPR project, but didn't have to use a Window's machine. I rather used Android tablets, connected the Barcodes directly to each one's OTG, and had a central Apache running my PHPR project. The idea was the same, JS event that intercepted the input. Most barcode devices can support prefix/suffix characters.
