3.3.2 Text RTD

The Text RTD type is a simple format that can be used for many purposes. Some examples include transmitting the results from a sensor measurement or sending a promotional message about a product.

The format for the Text RTD type is discussed in the NFC Text Record Type Definition (RTD) Technical Specification. See Example 4 for an example of a properly formatted Text RTD.
