Stocard / Klarna Import

[ComputaBloke]

Thanks for a great FOSS app!

Since I found a few other thread, but couldn't find a comprehensive documentation on this, I wanted to share more information on the "Stocard Import (BETA)" function, in the hope this helps other users.

Be aware that in the last month or so, Stocard has been acquired by Klarna.
Personally, I didn't want to migrate my card-wallet data to another proprietary app like Klarna, intruding on privacy and pushing things I don't need in a wallet, like: store brochures, commercials, promotions and ads, achievements and referals, so I thought better to remove my data altogether.
I was very glad to find Catima card and ticket manager via F-Droid, which can fill the primary needs for a digital wallet, and migrate the necessary card data without having to re-scan all my cards.

The Stocard Import function can be found under Catima's home screen: The ... menu > Import/Export > Import from filesystem > Stocard (BETA)

The Catima UI for this import method describes the process. There is unfortunately no direct 'Export' function of the Stocard app.
So the first step requires a manual action to Email the Stocard support address asking for export of your data.

Catima mentions the support address: [email protected] and this seems to still work, but they will redirect it and respond from: [email protected]

When you email support requesting data export, you must send the email from the email address which was used to create the Stocard account. I had used a Gmail alias address, so first had to add this address to my Gmail "Send mail as" settings, and then select that as my From address.

A member of the Customer Support team will reply by email with a ticket number. They will acknowledge your request for data export under a "Data portability request (Art. 20 GDPR)", which they are required to process within 30 days.

In my case, I received a data file and password after about 18 days.

The zip file contains a specific folder structure. Catima will expect it to be in a known format.
/extracts/<user-UUID>/users/<user-UUID>/
Further specs as mentioned in the "importZip" method, here:

Android/app/src/main/java/protect/card_locker/importexport/StocardImporter.java

Line 166 in c2ff763

Known files:

Download or copy the Zip file to your Android device filesystem.

Use the Catima Import/Export process to then select the Zip file from local filesystem.
When importing this Zip file, it will prompt for the Zip password. Enter this.

In my case the existing cards imported perfectly!
The Import includes barcodes or QR, notes, front and back images.
Reading the source-code comments, it seems the main gap in BETA for the moment might be the import of store balances/credit amounts, but I didn't have any of these so it was not an issue.

Sylvia, Catima's lead maintainer, has some further pointers in this thread if you face any challenges with this!

Hope that helps, and thanks again!
