A name-value line, with one text adjusted to the left, the other to the right:

Receipt Line
{
"type": "name-value",
"value": {
"name": "Kartennummer:",
"value": "9276004429942845",
"decoration": []
}
}

Name and value shall be printed at the same line. The name is adjusted to the left, and the value to the right.

Name-value lines can have the decoration important. Here goes the same like for normal text lines. It needs to be printed bolder.
