Processing a device with Workbench
==================================
Processing a device with the `eReuse.org Workbench
<https://github.com/ereuse/workbench>`_ means creating a hardware
report of the device (including serial numbers and other metadata),
linking the device with tags, and registering it to a Devicehub.
This is the first step when dealing with a new device with
the eReuse.org tools, as it registers the device with the database,
or updates its information if the device existed before. So any
other process, unless stated contrary, requires this one to be
performed to a device before.
For generic devices, the process is as follows:
1. The user opens the eReuse.org Android App (App) and selects
*add snapshot*.
2. The user sticks and scans the tags of the device, including the
:ref:`tags:eTags`, manufacturer tags (like serial numbers), and
tags provided by third-parties like donors.
3. The user manually introduces other information, like ratings,
and submits the information to Devicehub.
For a computer, `This video <https://vimeo.com/250253019>`_ explains
the process using generic tags, and it is as follows:
1. The user connects the computers to process to an eReuse.org Box
running the Workbench Server software using a local network.
2. Computers boot and automatically execute the eReuse.org Workbench
software, generating information from the computer and its components,
erasing the data storage components, testing the machine, etc.
3. During the process, the user opens the Android App and selects
the *Workbench* option, which connects the App to a running
Workbench Server in the local network.
4. From now on, like in step 2. from the generic device, the user
sticks and scans the tags from the device, specifically the
:ref:`tags:eTags` and the ones provided by third-parties. The
manufacturer tags are not required as such information is taken
by the Workbench automatically.
5. Android App and Workbench embed the information into a report
that is submitted to Devicehub.
Preparing a device for use
==========================
Users, like refurbishers, ready the devices so they are suitable
for trading. This process implies repairing, cleaning...
1. The user scans the tag of the device with the Android App or searches it from the
website and selects *actions* > *:ref:`actions:ToPrepare, Prepare <ToPrepare>`*,
which informs Devicehub that a device has to be prepared for trading.
2. The user prepares the device. Upon success, it performs the action
:ref:`actions:ToPrepare, Prepare <Prepare>` in the similar way that
did in 1.
3. A prepared device might still not be ready for trading. For example,
a seller still might want to clean a device once a trade has been
confirmed, as the device would have gathered dust between the
preparation and the trading. To denote a final "this device is
ready to be shipped to a customer state", the user performs
the action :ref:`actions:ReadyToUse` in the same way it did in 1.
If the device is broken or breaks, the user performs the action
:ref:`actions:ToRepair` denoting that the device has to be repaired,
and :ref:`actions:Repair` upon success.
Broken devices that are not going to be fixed might be set for
:ref:`Dispose a device <disposition>`.
Track a device
==============
:ref:`processing a device with workbench` registers into Devicehub
the required metadata from a device to identify it: a digital
passport for the device (information submitted in a Devicehub),
plus a physical passport (a tag that links the device with the digital
passport). If the physical passport is an :ref:`tags:eTag` then
it is unforgeable.
The rest of the traceability is based in keeping track of the events
occurring on the device, for example when it changes location or
it is traded. eReuse.org allows recording these actions, providing
mechanisms to ease them or ensure them. Please refer to the specific
use cases for more information.
Checking device authenticity
============================
Any user can check the authenticity of a device registered in a
Devicehub, even if the user is external, like a customer.
If the device has an :ref:`tags:eTag` or a regular tag generated by
a Devicehub (stuck on the :ref:`Processing a device with Workbench`),
the process is as follows:
1. The user scans the QR code with a smartphone using a generic QR
codes scanner.
2. The scanner opens the browser and takes the user to a webpage
containing public information of the device. Part of this
information are the serial numbers and other IDs of the device,
and a set of instructions in how to challenge the Photochromic
tag of the device, if the device has one stuck, to double-check
its veracity.
3. The user tests the photochromic tag by touching the flash bulb of
the smartphone with the tag for, at least, 6 seconds, checking
that the tag changes color temporarily.
Other ways of checking device authenticity are:
- Scanning the QR code stuck and comparing the serial numbers of the
device with the ones of the public webpage.
- Directly applying the photochromic challenge.
Workbench and Devicehub detect changes in computer components. Certain
scenarios where the computer passed by untrusted users require
ensuring that no component has been taken.
A deeper verification process is re-processing the computer with
Workbench, generating a new report that updates the information of
the computer in the Devicehub, ultimately showing the differences
in removed and added components.
Finally, the eReuse.org team is developing, using the platform Evrythng,
a global record of devices, which takes non-private IDs of the devices
of participating Devicehubs and records the most important life
events of the devices. This database is publicly available, so
users can search on it an ID of a device, for example the S/N or the one
written in a tag, like an :ref:`tags:eTag`, and know which Devicehub
registered in, ultimately accessing the public information of the device.
Recover a lost device
=====================
Users can recover a lost device found in a waste dump by following the
process of :ref:`checking device authenticity`.
A Devicehub participating in the global record of devices (explained
in :ref:`checking device authenticity`) automatically uploads public
device information into Evrythng. If the device was previously
registered in another Devicehub and there is no record of trading
between Devicehubs, Evrythng warns both systems. Note that this
functionality is in development.
Rating a device
===============
@ -35,23 +163,23 @@ action, which includes a guessed **price** for the device.
There are two ways of rating a device:
1. When processing a computer with Workbench and the Android App.
1. While Workbench is processing the machine, the user
links the tag with the computer. In this process, as it requires the
user to scan the tag with the App, the app allows the user to introduce
more information, including the appearance and functionality.
2. The App embeds the rate with the device report generated by the
Workbench.
3. The Workbench uploads the report to Devicehub.
2. Anytime with the Android App or website.
- The user scans the tag of the device with the Android App.
After scanning it, the App allows the user to rate the
appearance and functionality.
- Through the website, the user searches the device and then
selects to perform a new :ref:`actions:ManualRate`, rating
the appearance and functionality.
When processing a computer with the Workbench, once the user scans the
tag, it is showed with a screen where it can rate the appearance and
functionality. Once done, this data is added to the report of the
Workbench, which includes the automatic performance grade, and it is
uploaded to Devicehub, computing the :ref:`actions:Rate` with the
final total rate and guessed price.
.. todo this is not done yet
The second way is opening the App, scan the tag of the device, and
then select *rate* to write the appearance and functionality. The
same process can be done through the website by searching the device.
Note that with this process there is no way of introducing the
performance, as it is computed by Workbench, meaning that Devicehub
takes the last known performance value to compute a new Rate.
In any case, when Devicehub receives the ratings, it computes a final
global :ref:`actions:Rate`, embedding a guessed price for the device.
Refer to :ref:`actions:Rate` for technical details.
