====== RoadRunner - Writing an NFC Tag ======
</WRAP>

This page will explain how to write an NFC tag for customers using the electronic call monitoring system - RoadRunner. It is vitally important to ensure NFC tags are written properly to ensure a smooth and successful sign in/out process at the clients residence.

===== Downloading the NFC Tools App =====
In order to successfully write an NFC tag, you must download the correct tag writing app on an android handset. If you already have the correct app then go to the next section of this page.

1. Go to the **Play Store** app on your android handset to download the correct tag writing software

{{ :wiki:2019-01-04_10h31_19.png?600 |}}

**1** = indicates that this is for a client\\ 
**Company ID** = this is a 4-digit number that is provided from CareFree\\  
**Client ID** = this is taken from the Client’s record in CareFree\\ 
//The Client’s ID is stated next to the Client’s Forename field as shown below://
{{ :wiki:2019-01-04_10h33_07.png?300 |}}
**Client Name** = this is the Client’s Forename & Surname.

For example:

<WRAP center round important>
There must only be 3 commas in the data in those exact positions. If too many or few are written the tag will not be processed by the RoadRunner application. The name cannot have any commas in either. The sequence in which the data is written must be in that format above. For example, the Client ID cannot come before the Company ID etc.

10. Now that you have written your first tag, the best way to carry on writing more tags is editing the current record, if you add a new record it will try to write two records to one tag which you don't want. Instead click on the record you have added previously:

11. Now click the edit button:

12. Simply edit the id to your new clients details, press OK and then write as above. You then rinse and repeat this process until you have completed the tags. 

===== Password Protect a Tag =====

1. From the main menu, click **Other**, and then simply press Set password, hold the phone near the NFC until you get a success message. We recommend doing this to all tags to prevent erasure, we also recommend this over locking the tag permanently.

===== Erasing a Tag for re-use =====

1. From the main menu, click **Other**, and then simply press Erase tag, hold the phone near the NFC until you get a success message. Make sure to keep a distance from other tags you do not want to erase otherwise you will need to re-write them.
