The user should only be able to read or copy the nfc tag entries of a specific nfc tag with my app. Is that possible? And is it possible to make the tag read-only? NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to the reader in the form of electromagnetic pulses. You can't really prevent copying the user memory for ndef formatted tags. UIDs are read only for normal tags, but there are nfc tags with rewritable uids, so you need to check for . You have MIFARE Ultralight C tags. These tags have functionality that allows one to protect access to data stored on the tag to be protected by 3DES-based authentication. .

Such tags are intended as containers for freely readable data (so called NDEF messages). Anyone could read an NDEF message from one tag and duplicate it to another tag.Yes, many tag types permit write protection, some globally, and other more sophisticated ones by memory section inside the tag. When you get your tag detected in your Android NFC app, then you can get a Tag object and read and write to the tag, including protecting it from further writing.
I created an application that can read and write NFC tags. I want to ensure the tag is not copied or overwritten by another application or format. I found an application called "NFC Tools" which has "Set password" and "Remove password" features.
nfc tags not copying
Tags which do not make use of password-protection or over-the-air (OTA) encryption can have their data banks copied into new tags. RFID tags (at least Class 1 Generation 2 tags, aka UHF RFID tags) are computationally active, not passive. Their "passive" nature refers to their not needing an attached power source. While a standard NFC tag can be used to identify a product or item, there's nothing (generally) to prevent it from being duplicated into hundreds of counterfeit products. An authentication tag cannot be copied so each product has a substantially increased level of counterfeit protection. There are two common ways to prevent tampering in NFC cards: locking and blocking. Locking involves one-time programmable (OTP) lock bits that make it impossible for unauthorised users to change the memory permanently. Blocking is very much similar to locking.
