推荐答案

是否部分正确.取决于您使用的 NFC 标签，有 4 种不同的 NFC 标签类型适用于不同的协议技术.您可以在以下 链接.

Is it partially true. Depends on the NFC tag you're using, there are 4 different NFC tags types working in different protocol technologies. You can check it in the following link.

正如我在规范中看到的，RC522 支持 ISO14443A 和 MIFARE 产品的所有变体.

As I can see in the specs, RC522 supports ISO14443A and all variants of MIFARE products.

如果我没猜错(很长时间没有使用 NFC):

If I'm not wrong (long time not working with NFC):

• 类型 1:您无法扫描这些标签
• 类型 2:您可以扫描这些标签(基于 Mifare Ultralight)
• 类型 3:您无法扫描这些标签
• 类型 4:您可以扫描部分而非全部标签(部分基于 Mifare DESFire)

由于 2 类和 4 类 NFC 标签通常基于 MIFARE 标签，因此您应该能够扫描这些类型的标签.

As Type 2 and Type 4 NFC tags are based on MIFARE tags in general you should be able to scan those type of tags.
