The rice bracelet, 4 NFC, can’t wait to find a cow and buy one.
The NFC has three main functions: little friend, bus, simulator.
As a result, the hyenas are difficult to use, their functions are lacking, their response is slow, and Shanghai bus is not supported.

It’s like life.

The first one is an ID card, and I hope it’s all on the second encrypted IC card.
Put encryption card on PN532 to read data
Use MifareOne Tool decal

And where’s the coolest?
Refrigerator
After a long wait, it worked.

Get Encrypted Card Data

Then write 0 sector 0 data to a blank card

Then you write the data from the blank card in the bracelet.

There’s a card on the bracelet, but there’s only 0 sector 0, and it’s time to write the rest into the bracelet.

Only part of 0 sector 0 block (producer number) differs, and 15 sector sectors have the same encryption data, indicating that the simulation has been successful
At last, the NFC didn’t buy it for nothing.
