NXP’s NTAG213 chip is the most popular NFC chip for use with NFC tags and mobile phones. It’s full-featured and has more than enough memory for most applications and web addresses. Therefore, the costs associated with the mass production of this chip and tags with this chip mean that it’s a great value chip.
Probably! Android devices have supported NFC since the early days of the smartphone, but Apple chose to withhold support on the iPhone. However, when the company unveiled Apple Pay, a contactless payment system enabled by NFC, they began including these wireless chips on iPhones. Before iOS 11, the company limited its use just to Apple
NDEF (NFC Data Exchange Format) The NFC Data Exchange Format (NDEF) is a standardized data format that can be used to exchange information between any compatible NFC device and another NFC device or tag. The data format consists of NDEF Messages and NDEF Records. The standard is maintained by the NFC Forum and is freely available. Source: Adafruit
On NTAG21x, there are 4 bytes allocated to the password.The range is 00 00 00 00 to FF FF FF FF, which means there are 4 294 967 296 possibilities.For example, on an NFC reader which takes 200ms to communicate with the chip, it will take approximately 27 years to brute force the password.

NFC stands for Near Field Communication. NFC is only activated when your phone or other smart device is right next to a terminal or an NFC tag so you have complete control over what you choose to connect to.
NFC (Near Field Communication) technology makes your smart device smarter. It allows you to connect to a world of convenience, information, and enhanced experiences with just one tap.
During setup, go to your setting menu, look for NFC (sometimes listed under “more”), turn it on, and you’re ready to go. There are no apps to download or codes to enter. And NFC does not drain your battery.
An NFC tag is an unpowered microchip that is embedded in a product label, retail display, a smart poster, or most places where you see this symbol (N-Mark). With just a tap from your smartphone or other NFC-enabled device, NFC tags deliver enhanced product information, activate special offers, and power interactive experiences at museums or
