TRF7961: Detect ISO15693 Card without real readout only use it as trigger

Hello,

I have a very "simple" application.

I have to detect if an RFID card ISO15693 is next to the antenna. There is no need for me really
to read or write data. I only need the RFID card (ignoring the unique ID or any other data on it)
to use it as trigger. So I only need a trigger signal like an interrupt line ors so.

Is it possible to use a high integrated chip with integrated read/write features and simply
use it's IRQ line ? Because I do not want to configure this chip with an microcontroller.

Any idea ?

Thanks
