smartcard reading

Contactless card reading api's for xamarin

Hi guys,

I tried to find api for reading and writing data in to cards( tap to read or scan the card data and writing into it) but no where mention api for it, perhaps i would use tc52,56 or 57 device, i tried for searching on google and all other mediums but no clue to do it, NFC i heard but i tried to find it in api , no luck
kindly help me for card reading strategies or if i am missing, interpreting wrong let me know the approaches.
