由于NTAG21x标签IC具有高输入电容，因此该产品尤为适用于要求具有小尺寸的应用，而不会降低性能。小型NFC标签可更轻松地嵌入产品标签或电子设备等目标中。Thanks to the high input capacitance, NTAG21x tag ICs are particularly tailored for applications requiring small footprints, without compromise on performance. Small NFC tags can be more easily embedded into e.g. product labels or electronic devices.

防干扰Anticollision
智能防干扰功能允许在场内同时操作多个标签。防干扰算法分别选择每一个标签，并确保选定的标签正确执行交易，不会因为现场存在另一个标签而受到干扰。An intelligent anticollision function allows operating more than one tag in the field simultaneously. The anticollision algorithm selects each tag individually and ensures that the execution of a transaction with a selected tag is performed correctly without interference from another tag in the field.
非接触式电能和数据传输Contactless energy and data transfer
仅当IC连接天线时，才能建立NTAG21x通信。
Communication to NTAG21x can be established only when the IC is connected to an antenna.
NTAG21x位于RF范围内时，高速RF通信接口允许数据的传输波特率为106 kb/ s。
When NTAG21x is positioned in the RF field, the high-speed RF communication interface allows the transmission of the data with a baud rate of 106 kbit/s.
