### 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
~~~
```
 
##### Messenging services
1. **SMS**
```ad-command
~~~bash
smsto:< PHONE NUMBER > ,text
~~~
```
 
2. **Whatsapp**
```ad-command
~~~bash
https://wa.me/< PHONE NUMBER > ?text=< urlencodedtext >
~~~
```
 
3. **Signal**
```ad-command
~~~bash
https://signal.me/#p/+< PHONE NUMBER >
~~~
```
 
4. **Telegram**
```ad-command
~~~bash
https://wa.me/< PHONE NUMBER > ?text=< urlencodedtext >
~~~
```
 
5. **Email**
```ad-command
~~~bash
mailto:< EMAIL ADD > ?subject=< SUBJECT > & body=< BODY >
~~~
```
