Read someone's card and clone the serial number. Intercept communication between the legit card and the legit reader. Make a guess based on other cards from the same batch (that's why similarity between serial numbers also matters).
The NFC chip UID is a manufacturer supplied, usually read-only unique identifier for the NFC chip used to uniquely identify and NFC tag in a project’s software systems. The UID is also an important part of NFC security and anti-cloning. The UID of an NFC tag is a worldwide unique serial number. It should therefore be impossible to read out the UID and program it on other NFC tags (UID cloning). In fact, however, there are some (not original NXP) chipsets that allow the free configuration of the UID. I am trying to implement an authorization system based on general NFC tags. One of the concerns I want to address is tag cloning. I have read some literature ensuring tag authenticity by using a read-only tag ID written on the tags during manufacture.
NFC Tag UID Scan. Each NFC tag that we sell and many of the NFC tags on the market contain an effectively unique seven byte unique ID. Seven bytes equates to 14 hexadecimal characters. A hexadecimal character is a number from 0 to 9 or a letter from A to F.
Many NFC tags also contain a unique identifier that is pre-programmed by the tag manufacturer and cannot be modified on normal tags because those memory segments are in read-only memory. Such a unique ID could be used to uniquely identify a tag (i.e. to match the ID against some form of database).Another thing that makes NFC tag different is its Unique ID (ID). It is located in the first two pages of the NFC tag's memory. The UID is a unique code of the NFC that cannot be changed or deleted. The UID is unique worldwide, read-only and can be read by most NFC devices and all NFC-enabled smartphones. The UID cannot be deleted or changed, so that each NFC chip is unmistakably marked. In this article we explain how to read the UID with iOS, Android and a Windows systemThe NFC chip UID is read by a device from an NFC chip either by reading a specific portion of memory, by calling an NFC chip command or from a software subsystem that performs one of these; which method is used is based on the NFC tag type and NFC chip type.
