How Herz P1 Smart Ring Can Transform Your Health

The issues is 99.9% of entry cards (where I leave at least) are default-encrypted mifare classic, making cloning trivial. These are principally a single antenna wired to an array of chips directed by a keypad. That seems viable on paper however you continue to get to hold the card and press the suitable switch.The perfect answer would be a smart ring with a reflashable NFC chip, along with a programmable MCU to implement the rolling logic between playing cards. Reflashing the NFC chip on the ring is a bit of a ache (it takes a second, but if I need to spend a second doing it day by day, I'd as well get my keys out). Since every cellphone has an NFC chip these days, though, can't we use that to emulate all our Mifare playing cards? Mifare cards?Sadly, no.From my Herz P1 Experience not less than, most entry playing cards are easy mifare traditional playing cards, and so they have no payload: the reader just got an inventory of allowed card IDs, maintained by the building IT.Whereas you'll be able to freely rewrite mifare information from Android, it won't let you modify your ID except you root your phone.
