"So, this gold badge might be a device similar to an NFC access card! You just need to get close to an NFC reader, and it can read the information inside!"
Lin Xian directly took out his phone from his pocket.
Nowadays, the vast majority of phones already support NFC swipe functions, and can even emulate NFC signals. It's no longer high-end technology.
Of course, the NFC emulator on the phone can only simulate some simple, unencrypted NFC signals, such as access cards and the like.
As for encrypted cards such as meal cards, bank cards, ID cards... those kinds of NFC signals, don't even think about simply emulating them, they are difficult. The higher the encryption level of NFC, the less likely it is to be hacked and copied.
After taking out his phone,
Lin Xian directly brought the gold badge close to his phone—
Beep beep!
The phone emitted a soft sound, automatically detected the NFC signal, then the browser APP popped up, starting to bounce through webpages incessantly!
