This 35mm circular white NFC Sticker is backed by an NTAG213 chip. It is made of high quality PET which can be used in outdoor settings (it is water resistant) and stores up to 144 bytes of user data which can be made read-only.
It is also metal-isolated, which means it can be placed directly on metal. It will work on metallic surfaces such as your macbook pro.
