How to Work with Processes > Working with the NFC Processes Group

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 "NFC" action.

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 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 type of the tag 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 tag that was read.
Raw Data	Click and select/create the variable that will store the raw data contained in the tag 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. When defining a screen as a target destination (ex: via a “Go to” process), you CANNOT use variables to specify the name of that target screen. You must select the intended screen from the available drop-down/list.
Not Found	Select a target destination, in case the defined record is not found in the NFC tag, from the drop-down or list. When defining a screen as a target destination (ex: via a “Go to” process), you CANNOT use variables to specify the name of that target screen. You must select the intended screen from the available drop-down/list.

Detail of a window:

"S:Menu" is a screen included in the same program as the process.

"R:Routine_1" is a routine included in the same program as the process.

If required, click to attach any relevant notes to this process. Click it and enter your notes in the resulting text box. These notes will be displayed in the corresponding "Actions" tab or "Process" window (in the "Notes" field) and in the "Developer Report".

After filling in the required options, click to conclude or to abort the operation.

The added process is displayed in the corresponding "Actions" tab or "Process" window.

If you want to use a label as a target destination, you can use the "Auto-Label" mechanism. This alternative to the "Set Label" process allows you to create a label in the properties window of a process - specifically, in the fields used to define target destinations (ex: the "If Error..." type fields). See To Automatically Create a Label.

Use the right-click in MCL-Designer's input boxes to access some related options as well as the general "Cut", "Copy"; "Paste"; "Search" actions (active/inactive according to the current context).

Ex: If you right-click the "Variable" input box (included in a "Conversion's" properties window), you are provided with general editing/search actions and other more specific options such as "Variable Select" (see "Variable Select"); "Variable Insert" (see "Variable Insert"); "Insert Special Character" (see To Insert Special Characters into a Control's Text Input Field) and "Localization Select" (see Localization List).

If you right-click another input box, it may provide other possibilities.
