Generate EPC-compatible QR codes for wire transfers

Create QR codes for wire transfers

Sick of copy-and-pasting IBANs to forms? Why not just scan a QR code and have your favorite banking app take care of the rest?

Why not be generous and support wikipedia with EUR10? Grab your phone, open your banking app, select the QR scanner and scan the image below which was created with this tool.

The created QR code complies with the European Payments Council (EPC) Quick Response (QR) code guidelines.

1st Disclaimer: The author of this code has no affiliation with the EPC whatsoever. Henceforth, you are welcome to use the code at your own dispense, but any use is at your own (commercial) risk.

2nd Disclaimer: Currently, the EPC specifications are implemented only to work with IBAN-based consumer wire transfers within the European Economic Area (EEA), i.e. using the following pieces of information:

• Recipient
• IBAN
• Amount
• Unstructured remittance (aka reason for transfer)

Of course, any helping hand is welcome to extend the core functionality to more generic transactions.

Installation

To use the code as a standalone command line interface (CLI) tool, then use pipx as follows

pipx install py-epc-qr

You may verify the installation by calling epcqr version. The output should be identical to what pipx printed.

If you intend to use the code instead directly in your own Python projects, then install the package using pip

pip install py-epc-qr

Usage

You may use the package as a standalone command line interface (CLI) or as part of your own code.

CLI

Having installed the package with pipx (see above), you may verify the installation upon calling

>> epcqr --help

The core functionality lies behind create, for which you can call again the help.

epcqr create --help     
Usage: epcqr create [OPTIONS]

  Create EPC-compliant QR code for IBAN-based wire transfer within European
  economic area.

Options:
  --out TEXT        name of generated qr png file  [default: qr.png]
  --from-yaml TEXT  specify yaml file from which to create qr
  --help            Show this message and exit.

From interaction

If you call the create command without any options, it is started in an interactive mode. You are asked to input all relevant information. If your input is correct, an image will be created in your current directory.

From template

Alternatively, you can create the QR code from a yaml template, for which the repository contains an example.

Code

If you intend to use the source code in your own Python projects, then a minimal working example looks as follows:

from py_epc_qr.transaction import consumer_epc_qr
epc_qr = consumer_epc_qr(
    beneficiary= "Wikimedia Foerdergesellschaft",
    iban= "DE33100205000001194700",
    amount= 123.45,
    remittance= "Spende fuer Wikipedia"
    )
epc_qr.to_qr()

The relevant functions are gathered in transaction.py
