LET YOUR BUSINESS RELATIONS AND CUSTOMERSMANAGE AND CONTROL THEIR OWN VITAL DATA

The valueof accurate

customer data

Each company builds and maintains its own databases.

This is not only an extremely expensive and time

consuming process, it is also inconvenient for the

customer. Instead of rewarding loyal customers with

personalized and tailored offers, you burden them with

frequent requests to manually update their personal

data. Time and time again.

Only Once has solved thisFrom now on individuals can maintain and control their

own personal data. They decide which data they share,

when, with whom and for how long. Once they share

specific data with you, your organization can rely on its

accuracy. Any change, for instance, in address or phone

number, will instantly and automatically be reflected in

the information you have access to.

Win-WinThe world is evolving from a so-called ‘push’ to a ‘pull’

model. People want to control when and with whom

they do business. We call this ‘the intention economy’.

They do not want companies to use their data without

their consent or without receiving anything in return.

With Only Once, the customer has better control and the

convenience of not having to enter his data, time and

time again.

At the same time, your organization will have updated

customer data at a fraction of the cost. The quality and

effectiveness of your business processes and communi-

cations improve. Your customers are happier, and your

profits increase.

No more costly and time consuming

updates of your database.

Your customers will do it for you.

Happily so.

Increasing your customer’s satisfaction, loyalty and lifetime value is essential

for the success of your organization. Personalized communications are key but

keeping your customer information database up to date, correct and complete

can be expensive and time consuming. No matter how hard you try: over 23% of

the data is permanently outdated, incorrect or incomplete.

The big picture:what’s happening?

Companies are storing and managing important personal data all over the placeOrganizations want to know their customers, how

to contact them, their preferences and their relevant

characteristics. Each company is individually collecting

and storing this information in ever growing databases.

The more customers, the more data - and the higher

the likeliness that this data will be incorrect or out of

date. Customers change addresses, credit cards, jobs

and other life-events at an alarming rate and companies

spend huge amounts of money, just keeping track.

Scattered dataCustomer data can reside in a variety of systems and

places. Recent mixed with old, structured mixed with

unstructured, private and sensitive mixed with public

data. What is where? And how do we know which data is

correct and can be trusted?

Wrong data, costly failuresEvery year approximately 25% of your customer records

change and become obsolete. No matter how hard you

try, you will never be able to maintain a clean database.

And wrong or outdated information has a direct

negative impact on your results.

Privacy concernsThe way personal data is currently being treated goes

against all the founding principles of the Internet. We

therefore feel that change is needed. We believe that

an individual’s personal information and personal data

can best be managed and controlled by this person. At

present, many organizations hold pieces of a person’s

identity information. But who exactly has what? And

how do these organizations manage and secure it? How

can a consumer be sure that his information never ends

up where it should not?

Consumers are increasingly unwilling to help

organizations fill and maintain their databases. But they

certainly are committed to keeping their own Personal

Data Store up to date and accurate.

“Every time someone registers or fills out a form to providepersonal information, it’s highly inconvenient for the customer and anincreasing burden to the receiving organization. Still, this happens over and over again. A waste of time and money, for everyone.”

Roel PeelsFounder and CEO of Only Once

Consumers no longer hand their data over. They keep it in their Personal Data Store and only share the relevant information when they want to. With Only Once, the individual regains control of his own

personal information. Only Once is a platform where

people can enter, store and share, securely and easily,

both their sensitive and highly private data as well as

their straightforward contact information. They decide

who has access to what information and under which

conditions.

Organizations that have been given access, can now

be sure that the information they see is accurate and

verified, always up to date and with the customer’s

consent to use it in a mutually agreed manner. No more

need for costly updating processes, causing errors and

high maintenance costs.

Automated personal data sharing:safe and convenient. Only Once is a safe environment where individuals can

store their personal information and share it with family

and friends, organizations, colleagues and business

contacts. They simply enter their information. Only

Once. And their contacts will do the same. All data is

updated by the contacts themselves. The Only Once

platform ensures that your existing core systems are

always properly and securely connected with your

customer base. As a result, your business processes run

smoothly as they are now seamlessly provided with

correct and current data from the source itself.

Regain trustCustomers no longer want companies to use their

data without their knowledge. Through Only Once,

companies are able to regain trust as they return

ownership and control of data to the customers. This

‘trusted’ relationship enables more effective and

mutually satisfactory business.

Laws and regulationsWith Only Once, organizations no longer have to worry

the ground up to be safe, secure and highly personal.

It’s been designed to hold and securely share any

Only Once will externally verify field content and

provide a mechanism to let other users know that

Once PDS and Only Once will protect it with the highest

possible encryption while sharing it with those parties

who need it and have been provided access.

“In this connected society, it’s hard to overestimate the value of someone’s online identity and personal information. Yet individuals are not in control of their own information and organizations are still storing the data in old standalone systems, designed fordifferent purposes. This doesn’t make sense.”
