NFC can be copied to other settings, how to fix this
Standard NFC tags using chips such as the NTAG213, NTAG215 or NTAG216 can have the user memory duplicated relatively easily. However, authentication tags such as the NTAG424 or NTAG223/224 use encryption keys to change the data on each scan. This means that if the data is copied, it's immediately 'out of date' - the data isn't static.
