#### <a name="ean_extended">Enabling extended EAN</a>
|
|
|

|

The default setting for `ean_reader` is not capable of reading extensions such
|
|
|
|
|
as [EAN-2](https://en.wikipedia.org/wiki/EAN_2) or
|
|
|
|
|
[EAN-5](https://en.wikipedia.org/wiki/EAN_5). In order to activate those
|
|
|
|
|
supplements you have to provide them in the configuration as followed:
|
|
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
|
decoder: {
|
|
|
|
|
readers: [{
|
|
|
|
|
format: "ean_reader",
|
|
|
|
|
config: {
|
|
|
|
|
supplements: [
|
|
|
|
|
'ean_5_reader', 'ean_2_reader'
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
}]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Beware that the order of the `supplements` matters in such that the reader stops
|
|
|
|
|
decoding when the first supplement was found. So if you are interested in EAN-2
|
|
|
|
|
and EAN-5 extensions, use the order depicted above.
|
|
|
|
|
|
|
|
|
|
It's important to mention that, if supplements are supplied, regular EAN-13
|
|
|
|
|
codes cannot be read any more with the same reader. If you want to read EAN-13
|
|
|
|
|
with and without extensions you have to add another `ean_reader` reader to the
|
|
|
|
|
configuration.
