* The NFC device will try to find the available passive tags. Some NFC devices are capable to emulate passive tags. The standards (ISO18092 and ECMA-340) describe the modulation that can be used for reader to passive communications. The chip needs to know with what kind of tag it is dealing with, therefore the initial modulation and speed (106, 212 or 424 kbps) should be supplied.
* @note For every initial modulation type there is a different collection of information returned (in nfc_target_info_t pointer pti) They all fit in the data-type which is called nfc_target_info_t. This is a union which contains the tag information that belongs to the according initial modulation type.

* After selecting and communicating with a passive tag, this function could be used to deactivate and release the tag. This is very useful when there are multiple tags available in the field. It is possible to use the nfc_initiator_select_tag() function to select the first available tag, test it for the available features and support, deselect it and skip to the next tag until the correct tag is found.
