### Characteristics
|
||
|
|
|
||
|
|
 
|
||
|
|
|
||
|
|
Zint is a Command Line Interface for generating QR codes.
|
||
|
|
It is installed through `brew` on my day-to-day Mac.
|
||
|
|
|
||
|
|
 
|
||
|
|
|
||
|
|
#### Command structure
|
||
|
|
|
||
|
|
The command is articulated as follows:
|
||
|
|
|
||
|
|
```ad-command
|
||
|
|
~~~bash
|
||
|
|
zint -b <CODE NOMENCLATURE> -o <PATH> --vers=<CODE VERSION> -d "<TO ENCODE>"
|
||
|
|
~~~
|
||
|
|
```
|
||
|
|
|
||
|
|
All parameters are well documented on the website of the provider of zint. A QR code has nomenclature 58, for example.
|
||
|
|
|
||
|
|
The `d` parameter is expanded a little further in the following section.
|
||
|
|

|
||
|
|
|
||
|
|
#### Data to encode
|
||
|
|
|
||
|
|
Originally designed for text or URLs, QR codes can encode more complex information that can be passed on. Below is a recap of a few useful ways to use a QR code.
|
||
|
|
|
||
|
|
 
|
||
|
|
|
||
|
|
##### WiFi credentials
|
||
|
|
|
||
|
|
Encoding follows this nomenclature:
|
||
|
|
|
||
|
|
```ad-command
|
||
|
|
~~~bash
|
||
|
|
WIFI:S:<NAME>;T:<WEP|WPA|else...>;P:<PW>
|
||
|
|
~~~
|
||
|
|
```
|
||
|
|
|
||
|
|
 
|
||
|
|
|
||
|
|
##### Geo-location
|
||
|
|
|
||
|
|
Encoding with relative coordinates:
|
||
|
|
|
||
|
|
```ad-command
|
||
|
|
~~~bash
|
||
|
|
geo:x.xxxx,y.yyyyy
|
||
|
|
~~~
|
||
|
|
```
|
||
|
|
|
||
|
|
 
|
||
|
|
|
||
|
|
