QR code – un codice a matrice introdotto più di dieci anni fa da Denso-Wave Corporation (Giappone), inizialmente utilizzato solo nell’industria automobilistica, ma la sua utilità è stata rapidamente apprezzata in altri settori. Un codice a barre non è altro che un’etichetta ottica che contiene informazioni su un oggetto e la lettura avviene con dispositivi speciali, nel nostro caso, una fotocamera di un dispositivo mobile. Il Codice di risposta rapida si presenta come una disposizione casuale di piccoli quadrati neri su sfondo bianco.
Questo codice a barre bidimensionale si trova ovunque nella vita moderna: nei centri commerciali sulle confezioni dei prodotti, sulle pagine delle pubblicazioni stampate e sulle risorse Internet. Utilizzando le informazioni crittografate in un codice QR, una persona può accedere rapidamente a una risorsa specifica, il cui collegamento è scritto nel codice, leggere un’e-mail, un messaggio di testo, scoprire le coordinate e così via. Nella maggior parte dei moderni smartphone e tablet, di default nel sistema è presente un programma che legge il codice a barre. Ma la comodità e la funzionalità di tali utilità non sono adatte a tutti gli utenti.
In questi casi, viene in soccorso un software alternativo, quindi l’utilità QR & Barcode Scanner ti consentirà di leggere in modo rapido e accurato qualsiasi codice a barre che consentirà, ad esempio, di collegarsi automaticamente a una rete Wi-Fi, accedere a un URL, leggere un numero univoco di un’edizione di un libro ( International Standard Book Number) e visualizzare le informazioni complete sul prodotto selezionato. Ci sono funzioni utili nel programma come l’accensione del flash, la messa a fuoco automatica, l’inversione del codice a barre, la visualizzazione dell’intera cronologia di scansione.
