Process Purpose

The Read NFC Record process is used to read a specific record in an NFC tag and store that information into variables.

Add this process to the "On NFC Tag Read" event.

This process is ONLY applicable to Android devices with NFC technology.

This process implies the use of an NFC profile and the "Enable NFC" process to prepare the MCL application for NFC tag reading.

See Example of "NFC Tag Reading" within an "MCL" Application).

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the Read NFC Record process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

Fill in the following options:

Read Record
Number	Select the appropriate NFC tag record from the drop-down list or click to select a variable that provides the record to be read. •The First Record” option places the pointer to the first record. •The“Last Record” places the pointer to the last record. •The "Current Record"; "Next Record" and "Previous Record" options depend on the pointer position defined in the previous "Read NFC Record" process. •If "Current Record" is used in the first "Read NFC Record" process, the pointer is set in the first record. Consider the NFC tag being used (the information it includes) when defining the record to be read.
Store into Variable
Type	Click and select/create the variable that will store the content type of the record that was read. See To Select/Create a Variable.
Text Data	Click and select/create the variable that will store the text data contained in the record that was read.
Raw Data	Click and select/create the variable that will store the raw data contained in the record that was read.
If ... Go to
Record Found	Select a target location from the drop-down or list, in case the defined record is found in the NFC tag. See Detail of a window below.
Not Found	Select a target destination, in case the defined record is not found in the NFC tag, from the drop-down or list. Ex: When trying to read the next record and pointer is already in the last record.
