China 2020 40th National Stamp Popularity Poll Miniature sheet with NFC technology 

Issue date 27 September 2020

China Post has issued its first postage stamp incorporating an NFC (near field communication) chip titled "In Commemoration of the 40th National Stamp Popularity Poll".

The miniature sheet has an ultrathin 120 micrometre NFC chip inserted within it. Stamp Collectors can download a digital app from China Post which can be scanned on any digital device with NFC functionality. By placing their device close to the number "40" that is on the stamp's face, the app will authenticate the stamp and provide information such as its serial number.  It is the world's first postage stamp with a read-write chip (note the words read-write chip - indicating the NFC can be written on with information from the China Post App). The NFC chip incorporated on the Humming Bird Stamp by Caribbean Netherland Post is a read-only NFC Chip.

NFC technology allows for the contactless exchange of data over close distances. Invented during the early 21st century, it has been commonly used around the world in areas such as the mobile payment and anti-counterfeit measure fields. 

Have tried to find the China Post App but have not yet been available to find the link to the stamp for download. However, have tried reading the NFC chip with a third party NFC App available on the Net just to detect the NFC Chip on the miniature sheet.

Video is just to show detection of the NFC chip

You can see the embedded chip when raised the stamp against a light source and you will see the shadow of the embedded NFC chip in the miniature sheet

Tried to check the stamp serials with a Smartphone with NFC detection capability but it gives a message of Error in Reading the NFC chip. I guess I need to find the China Post App.
