●Overview
●The NTAG I2C was the first product of NXP’s NTAG® family offering both contactless and contact interface. Meanwhile NTAG I2C _plus_, which is fully backward compatible, but with extended feature set and improved interoperability is available. For new projects NXP recommends to use NTAG I2C _plus_.
●More information about NTAG I²C applications and use cases can be found in brochure "NFC for embedded applications".
