# Cards
|
||||
|
||||
Basic viewer for loyalty cards synced from Catima through GadgetBridge.
|
||||
The app can display the cards' info (balance, expiration, note, etc.) and tapping on the appropriate field will display the code, if the type is supported.
|
||||
|
||||
Double tapping on the code will come back to the visualization of the card's details.
|
||||
|
||||
Beware that the small screen of the Banglejs 2 cannot render properly complex barcodes (in fact the resolution is very limited to render most barcodes).
|
||||
|
||||
### Supported codes types
|
||||
|
||||
* `CODE_39`
|
||||
* `CODABAR`
|
||||
* `QR_CODE`
|
||||
|
||||
### How to sync
|
||||
|
||||
_WIP: we currently cannot synchronize cards_
|
||||
|
||||
You can test it by sending on your bangle a file like this:
|
||||
|
||||
_android.cards.json_
|
||||
|
||||
```json
|
||||
[
|
||||
{
|
||||
"id": 1,
|
||||
"name": "First card",
|
||||
"value": "01234",
|
||||
"note": "Some stuff",
|
||||
"type": "CODE_39",
|
||||
"balance": "15 EUR",
|
||||
"expiration": "1691102081"
|
||||
},
|
||||
{
|
||||
"id": 2,
|
||||
"name": "Second card",
|
||||
"value": "Hello world",
|
||||
"note": "This is a qr generated on the bangle!",
|
||||
"type": "QR_CODE",
|
||||
"balance": "2 P"
|
||||
}
|
||||
]
|

```
