There may be requirement that a QR Code needs to be generated in a field.
Say, for Contact record in Salesforce. With the Contact informations available, a QR Code will be generated.
First we need to know what is QR Code?
http://en.wikipedia.org/wiki/QR_code
Now in Contact:
Field APi Name: QRCode__c
Data Type :Formula
IMAGE('https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=MECARD:N:'
+ FirstName + ' ' + LastName +';ADR:'+ MailingStreet +',' +
MailingCity + ',' + MailingState + ',' + MailingCountry + ',' +
MailingPostalCode + ';TEL:'+ MobilePhone +';EMAIL:' + Email + ';',
'Scan the QR code to create contact in your mobile' )
Now you just scan the QR code coming at you COntact record and see how it works!
