Code d’Identification (CI) — GS1 128
Grâce à l’utilisation du système de formatage GS1-128 est ajouté un CI (Code d’Identification). Il s’agit d’un nombre attaché au début d’une série de données afin d’informer, le scanner du type de données scannées.
Par exemple vous pouvez encoder le poids de 35,97 kg avec un code-barres classique en utilisant 3597, mais pendant la lecture il ne sera pas possible de savoir s’il s’agit d’un point, d’un temps, d’un prix ou d’autre chose, dans les faits, l’application n’est pas capable de comprendre ce qu’elle est en train de lire. Le Code d’Identification est sensé résoudre ce problème.
Les normes GS1 encadrent un bon nombre de CI, tel que les numéros de série ou les dates d’expiration.
Tableau des Codes d’Identification GS1
Le tableau ci-après contient une liste de CI courants (Codes d’Identification). Certains CI sont suivi par un « n » ou un « y » : cela signifie que le CI peut être ajouté à un chiffre pour avoir les significations suivantes :
- n: le chiffre indique la longueur du champ de données.
- y: le chiffre indique le rang de la virgule des décimales.
