Supported passive RFID tags at a distance from Android phones with NFC?

Is there any way for an NFC Android phone (Nexus, Galaxy, etc.) to read a passive RFID tag designed to be read over a long distance? I am interested in using the same tag that can be read by a RFID reader over a long distance and an Android phone with NFC at a shorter distance.

Does such a tag exist? So how can I read and write using the Android SDK since this is not a typical NFC tag?

Nexus NFC devices support ISO15693 tags. The ISO15693 characters are blizzard tags and provide a maximum reading distance of 1-1.5 meters (depending on the reader's antenna). Nexus devices have a reading range for these tags, comparable to other NFC tags: a maximum of a couple cm.

Android supports NDEF content stored on some ISO15693: NXP ICODE tags . The Android Ndef class technology will take care of reading and writing from / to such tags and automatic detection, as for other NFC tags. Details on how NDEF is stored in ICODE tags are available at http://www.nxp.com/documents/application_note/AN11042.pdf and http://www.nxp.com/documents/application_note/AN11032.pdf .

The antenna of mobile NFC devices will be detected only in the range of centimeters. 4-10 cm.

Could you explain why you want this work to work?
