### Changes to Code
:::warning
Ended up making a delete function in addition to the planned ones ([can be referenced here](https://hackmd.io/@tiffanycheng/ry3LHLn55))
:::
**Delete Function**
* A delete function was added to delete all occurrences of the unregistered user with the additonal card ID in `members_data` as designed in flowchart(See Figure 2).
* Had to double check with Ren about how to identify if a user is unregistered.
* Originally thought there would be a delete function in `XinxingQt.py` since it is served to query and update the collection. However, it did not include one.


**Main Method**
* Previously prompted the user to input the primary card ID before adding data to the `members_addtional_card` collection.
* However, this is highly subject to error due to user input.
* The user input may be wrong.
* Checking if the input they enter is correct is too tedious.
* Instead, it is easier to find when the `primaryCard` field is equal to the `additionalCard` field.
* Then, take that field and put it in the collection as the `primaryCard` for the user.
* This translates to the long search query using the and expression for when the `SchoolID` is `s and ` when the `primaryCard` field is equal to the `additionalCard` field.
* The partition is conveniently set upso that index `0` of `index[2]` is the first digit in the primary Card ID.
* The verify function is called again just to make sure the system has correctly extracted a 10 digit string.
* Added the last line to delete all occurrences of the unregistered user with the additonal card ID in `members_data`.

The domain for the [Smart Dispenser's MongoDB](mongodb://admin:bmwee8097218@140.118.122.115:30415/) was down so I could not test my code until the next day (7/8)
