CPU Usage of NxpNfcRdLib

We are using NxpNfcRdLib LINUX SW PACKAGE : (V04.06.00) and its various test apps with  Mifare cards connected to  CLEV663B Blueboard v3.0 modified to work over I2C on rapsberry pi platform. When running examples, such as NfcrdlibEx1_BasicDiscoveryLoop, they use a lot of CPU when no card is present. We of course have the interrupt line connected so I'm not sure why its using all this CPU polling different card formats (unless this is not what the interrupt is used for). Can anyone comment on this findings?

I promise we're not co-workers
