Session CD119 - Introducing QR-Codes in Your SAP System

This session will explain how it's easy, within the SAP Business Suite, to take advantage

of QR-Codes, the two dimensional bar codes that appear as patterned squares.

It's a good opportunity to learn about:

the QR-Codes basic concepts

the available options to generate a QR-Code both for printing (PDF) and for online

applications (Web images)

how to build the Web pages that will be presented to the mobile device (e.g.

iPhone, Nokia, Android, Blackberry) once a QR-Code is scanned

We will talk about possible business scenarios while scanning your first QR-Codes.

abap2qrcode - QR Code generator from ABAP

http://code.google.com/p/abap2qrcode/

the idea is to

wrap QR code

generators within

an HTTP ABAP

Handler

The ABAP

wrapper can

manage with

different

generators to fit

all the

requirements

abap2qrcode - QR Code generator via Google Chart API

http://sapecc.techedge.it/sap/zsdn_tags/qrcode? http://chart.apis.google.com/chart?

http http

From the browser, the QR Code images are coherently received from the SAP Web AS

All the resources are generated by the same host:protocol (e.g. HTTP /HTTPs)

Parameters:

t (type) = e.g. gc for google chart, others to be implemented

s (size) = e.g. 200 one dimension its enough

l (error correction level) = e.g. L it can be LMQH

c (content) = e.g. http://twitter.com/sapmentors
