passive nfc tag distance The reader detects the new magnetic field from the RFID tag and registers it. Many transportation systems and security systems use this sort of technology -- the RFID tag is in a card or fob that you must place near a reader to activate. This method is called passive RFID. In my project, we used ACR122 smart card reader that will be connect to a pc not android device.This reader is used to read any nfc tag. An nfc enabled android device will act as a nfc tag in card emulation mode. Now next part of question "The inbuilt NFC libraries support to that reader or not". so this card reader can read card value.

NFC Tools GUI is a cross Platform software : it works on Mac, Windows and Linux. You can read and write your NFC chips with a simple and lightweight user interface. Connect your NFC reader to your computer like the very popular ACR122U to start playing with your NFC tags.
It is possible to increase the read range by creating a much larger loop in the reader antenna. A larger tag antenna would increase the read range only slightly. Of course, if you want a read range of longer than 3 feet, you should consider using passive ultrahigh-frequency (UHF) RFID.

Most door badge readers are designed to require a distance of less than two inches. Near Field Communications (NFC), found in credit cards, cell phones, and other payment systems, use High Frequency (HF) which falls in-between the two, and they will have a range somewhere between the two.
Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less to initiate a connection. NFC lets you share small payloads of data between an NFC tag and an Android-powered device, or between two Android-powered devices.NFC tags are passive data stores which can be read, and under some circumstances written to, by an NFC device. They typically contain data (as of 2015 between 96 and 8,192 bytes) and are read-only in normal use, but may be rewritable. As a result, NFC devices can conduct passive communication, allowing them to interact with NFC tags or other devices without their own power source. It is important to mention that NFC communication requires devices to be in close proximity and aligned properly for effective data exchange.
Is there a way to calculate/estimate the physical distance to a long-distance passive RFID tag when reading it with a tag reader? E.g. to determine the order of books in a shelf, or telling if one object is close or far away.For transmission to a passive system such as an NFC phone in passive card emulation mode, the passive system uses the 13.56 MHz carrier signal of the polling device as energy source.
The Nexus devices with NFC all support ISO15693 tags. ISO15693 tags are vicinity tags and offer maximum read distance of 1-1.5 metres (depending on the reader antenna).
Passive RFID tag plays an important role in many fields with their advantages such as low cost, long life, and wide applicability. When choosing such tags, factors such as specific application scenarios, reading distance, and environmental adaptability need to be considered.It is possible to increase the read range by creating a much larger loop in the reader antenna.

There are a couple of NFC readers that will be able to read unencrypted cards. I personally use "NFC Tools". But sadly afaik there is no way to emulate on a nonjailbroken iPhone, since .
