|
||
The qrbill package implements generating QR-bill QR codes, which is a Swiss
|
||
🇨🇭 payment standard:
|
||
|
||
* [launch
|
||
announcement](https://www.six-group.com/en/newsroom/media-releases/2020/20200609-qr-bill-launch.html)
|
||
|
||
* [Specification: Swiss Implementation Guidelines
|
||
QR-bill](https://www.paymentstandards.ch/dam/downloads/ig-qr-bill-en.pdf)
|
||
\
|
||
(version 2.1 from 30 September 2019 at the time of writing)
|
||
|
||
These QR codes fill in details of a bank wire transfer, either all fields or
|
||
just some of them.
|
||
|
||
Recipients can scan the QR code with their mobile banking app, or with their
|
||
online banking web site’s mobile scan functionality, making it much easier to
|
||
send a wire transfer.
|
||
|
||
An example use case is for an association or club: you can send out payment
|
||
instructions to your members to collect membership fees (“Einzahlungsschein”).
|
||
|
||
## Validity
|
||
|
||
The [SIX QR-bill validation
|
||
portal](https://validation.iso-payments.ch/gp/qrrechnung/home) successfully
|
||
confirms that e.g. the code at the top right is valid.
|
||
|
||
## qrbill API (Example program)
|
||
|
||
To install the program:
|
||
|
||
```
|
||
go install github.com/stapelberg/qrbill/cmd/...
|
||
```
|
||
|
||
To run the program, run `qrbill-api` in the terminal. You will see an output like this:
|
||
|
||
```
|
||
% qrbill-api
|
||
2020/06/25 23:32:52 QR Bill generation URL: http://localhost:9933/qr?format=html
|
||
```
|
||
|
||
You can append the URL parameters on the left to customize the code. E.g.:
|
||
|
||
http://localhost:9933/qr?format=html&udname=Mary+Jane&udaddr1=Artikel+19b
|
||
|
||
When you open the URL in your web browser, you should see the following debug
|
||
output:
|
||
|
||
|
||
|
||
When you scan the resulting QR code with your eBanking app, you should see a
|
||
form like this:
|
||
|
||
<img src="https://github.com/stapelberg/qrbill/raw/master/img/2020-06-25-ebanking-app.jpg" height="300">
|
||
|
||
Once you are happy with the code parameters, change the `format` parameter from
|
||
`html` to `png`, e.g.:
|
||
|
||
http://localhost:9933/qr?format=png&udname=Mary+Jane&udaddr1=Artikel+19b
|
||
|
||
## Crowd-sourced compatibility testing
|
||
|
||
To build confidence in our implementation, please help us verify that the codes
|
||
scan as expected!
|
||
|
||
### qrbill v0.1.3 (2020-Sep-10)
|
||
|
||
Scan each of the following 3 QR codes in your eBanking app, program or web
|
||
interface, then file an issue (or send a pull request) with your test results!
|
||
Thank you very much.
