A vCard is an electronic business or personal card.

You may have seen a vCard attached to an e-mail or SMS someone has sent you.

Software application developers can create programs that process vCards by letting you view them, or drag-and-drop them to an address book.

vCards can include images and sound as well as text.

To open (look at) a vCard that someone has sent you, your e-mail program needs to support vCards and not all such programs do yet.

However, if you have an online address book or personal information manager that supports vCards, you can move your Vcard file to that program for viewing that file and storing it.

A promising future use of a vCard will be as a way to quickly fill in application forms on the Web.
Just drag-and-drop your own vCard to the form and you won't have so many blanks to fill in.

There is one more technology called vCalendar , a similar one, for personal time scheduling.

They look like this:

Quick-response codes, better known as QR codes, were introduced in the auto industry in Japan in 1994 to track vehicles during manufacture.

It is a customer engagement technique where the user scans the QR code box with their smartphone, and the mobile device takes the user to a designated site.

The first QR code scanner and reader applications for smartphones became available in the United States around 2010.

You may soon see QR Codes in a magazine advert, on a billboard, a web page or even on someone’s t-shirt. Once it is in your cell phone, it may give you details about that business.

WHY NOT BARCODE…??

The reason why they are more useful than a standard barcode is that they can store much more data, including url links, geo coordinates, and text. The other key feature of QR Codes is that instead of requiring a chunky hand-held scanner to scan them, many modern cell phones can scan them.

HOW DOES THE CELL PHONE READ THIS CODE?

The cell phone needs a QR code reader, like this one from Kaywa. It takes literally 1 minute for someone with an iPhone or Android phone to find and install the reader.

HOW CAN YOU GENERATE A QR-CODE?

You can easily generate a QR code using a site like Kaywa.com or you can use the Open Source codes to generate code for you. Google also provide many tools to develop QR code.

HOW COULD YOU USE A QR-CODE?

Your business, no matter how small or large, could use QR codes in a number of ways.

You could add one to your business card containing your contact details so its easy for someone to add you to their contacts on their cell phone.

Add them to any print advertising, brochures, posters, invites, TV ads etc containing:

Product details

Contact details

Offer details

Event details

Competition details

A coupon

Twitter, Facebook, MySpace IDs

A link to your YouTube video

WHY ARE QR-CODES UN-POPULAR ?

Lack of exciting content.

Users are experiencing that some companies’ QR codes are simply taking them to the company website or a boring ad. The users want a new and exciting experience when using this technology.

No built in QR scanner on the phones

Extremely popular phones for young individuals like iphone, Samsung Galaxy S 4, Sony Xperia, and some Nokia models, the lack of a QR code scanner adds more inconvenience for the user.

Bad locations.

QR codes need to be in an area where the customer has time to go through the process. This includes bus stops, subway stops, magazines, etc. Some QR codes are in places with customers in a hurry, or have bad cell service.

WHAT ARE THE OTHER OPTIONS FOR DIGITAL MARKETING?

Universal Product Code (UPC):-These are the standard bar codes on most items available for purchase, and can also be used for presenting information to consumers with a scanning device.

Near Field Communication (NFC):-These are smartphones similar devices that establish radio connection by touching together or close proximity.

Gee.Am:-This is a creative way for people or advertisers to transfer data to their mobile devices via audio signals.
