Setup

The process of setting up NFC based attendance recording or door opening at your university is as follows:

  • Reach out to us via email and let us know about your plans.
  • We provide you the appropriate number of NFC tags.
  • You register the NFC tags in Flow.
  • Place the NFC tags at the desired locations.

Tag placement​

You have complete flexibility in how you use the NFC tags. Here are some common applications for each module:

  • Door Opening System
    • Mount a tag next to the door on the wall.
  • Digital Attendance List:
    • Place them on the lecturer's desk.
    • Mount them to the wall next to the entrance door.
      For busy occasions, consider placing a tag on each side of the door.
    • Mount them on each row of seats.
    • Mount them on each individual seat.

Concepts​

Before we start with enabling NFC, let's shortly introduce the two building blocks for the NFC functionality in Flow:

  1. Tag: A tag in Flow represents an actual NFC tag. By creating a tag Flow can execute the corresponding action when the tag is scanned (e.g. check-in, open door).
  2. Door: A door can be thought of as a real door where NFC tags are placed. But it is not limited to this use. A door can also be the lecturer's desk. This way students would go to the desk and check in by scanning the NFC tag with their phone.

Flow Setup FAQ​

Prerequisite: Administrator or NFC tag manager permission.
To get the corresponding module working with NFC, set up the tags and doors in the Flow Configuration.

Which tags are supported?​

Currently Infineon Secora tags are supported.

How does the authentication work?​

To verify that the genuine tag is scanned, a challenge-response authentication process is performed.
There are two authentication options:

  • Studo Flow: The authentication is done on our side.
  • External authentication: The authentication is done on your side. (Contact us if you want to use this option.)

What is the JSON descriptor?​

The JSON descriptor contains the tag ID and the public keys for verifying the tag.

How to get the JSON descriptor of the tag?​

  1. Open the side menu in the Studo app, click on Get NFC tag descriptor and scan the tag by holding the phone to the NFC tag. (If you don't see this side menu item, make sure that you have the administrator or NFC tag manager permission.)
  2. Transfer the JSON descriptor from the clipboard to Flow.
