2

What is a mobile payment?  Mobile payment  a payment (transfer of funds in return for a good or service) where the mobile device is involved in the initiation and confirmation of the payment  includes P2P transfer of funds

 Mobile banking  access to banking functionality (query + transaction) via the mobile device  includes the provision of part or all of the banking functionality already provided by banks over the Internet in the form of online banking

 Mobile transaction  transaction where the mobile phone is used simply to initiate an order but not make a payment or to receive delivery of goods or services (e.g., event ticket bar code)

3

Mobile payments technology  Short Message Service (SMS)  SMS is a communication protocol

allowing interchange of short text messages  Problems as a mobile payment platform  Slow, store-and-forward operation  No security or encryption, sent in clear text only (except during transmission over the air)  No inherent proof or confirmation of receipt or delivery

 Generally used to purchase digital goods (ringtones, avatars, games) or send money P2P or P2B

Send money  Send a text to 729725 (PAYPAL). Specify the amount and the recipient’s phone number or email address.

Send money  Request money Send a text to 729725 (PAYPAL). Include the words get and from, and then specify the amount and the phone number of the person you’re requesting money from.

4

Mobile payments technology  Unstructured Supplementary Service Data (USSD)  USSD is a mechanism for transmitting information via a

GSM network  Unlike SMS, USSD offers a real-time connection during a session which makes it faster  Used extensively overseas for mobile financial services such as remittances and bill payment  Examples: M-Pesa in Kenya, TchoTcho Mobile in Haiti

5

Mobile payments technology  Quick response (―QR‖) two-dimensional barcodes

 Popular for closed-loop applications  Starbucks, Target, other retailers

6

Mobile payments technology  Near field communication (NFC)  NFC is a short-range high frequency wireless communication technology that enables the exchange of data between devices over about a 4 cm. distance  Allows emulation of existing contactless payment standards (MasterCard PayPass, Visa payWave, American Express ExpressPay, Discover Zip)  Allows P2P transfers (NFC device to NFC device)  Can read ―tags‖ from smart posters for offers or coupons

NFC business models  Mobile network operator centric model    

MNO independently deploys mobile payment service Can bypass financial institutions or develop open ―wallet‖ application Challenged by lack of connection to existing payments networks Generally limited to remittances and P2P

 Financial institution centric model  Financial institution develops a mobile payment application to be used on any mobile device  Ensures merchants have necessary POS capabilities  MNO involvement may not be necessary

 Collaborative model  Financial institutions, MNOs, and trusted service managers collaborate

to deliver mobile payment  Model favored by the Federal Reserve

 P2P model  Third party develops application to provide P2P or other form of mobile payment

Securing NFC mobile payments  Security critical applications that require payment

and account credentials need secure hardware storage and a secure execution environment  Role is handled by the secure element (SE)  A secure element is a platform where applications can be

installed, personalized and managed, which consists of hardware, software, interfaces, and protocols that enable the secure storage of credentials and execution of applications for payment, authentication, and other services

15

Secure element location options  On the universal integrated circuit card (or UICC)  Typically this is the phone’s subscriber identity module or

SIM.  MNOs have control of the UICC.

 On a separate chip or SD card inserted in the

phone.  Financial institutions have the option to be MNO

independent.

 Embedding the secure element in the phone itself.  Preferred option for the location of the Secure Element

NFC advantages…  Security  Multiple layers of security (secure element, PIN, additional

authentication factors [phone number, SMS challenge], information never passed as clear text

 Lower merchant liability costs  Mag-stripe data exposure is eliminated

 Lower issuer costs  No physical card distribution  Reduced fraud due to lost cards

24

Value proposition and challenges Customer is always ―on-line,‖ which allows for

 

Improved customer relationship management 



Increased yield from marketing spend 



Receipts sent to phone after purchase Co-marketing – purchase concert ticket and get a e-gift card for purchase of music on iTunes

Targeted offers 

 

Messages and offers can be sent to customer in conjunction with a transaction (e.g., rebate coupons, map to event just purchased) Paperless coupons Smart offers – customized offers sent to customers based on customers’ demographics and transaction history

25

Value proposition and challenges  Stakeholders have varying motives for pursuing mobile

payments  Financial institutions  Mainly a defensive play to protect current payment products  Prevent further disintermediation of the financial institution by

keeping financial institution involved in any solution developed  Reduction of transaction costs of existing payment methods, especially cash and checks

 Mobile network operators  Provision of value-added services to subscribers to reduce churn and increase average revenue per unit through associated increases in airtime and data usage

26

Value proposition and challenges  Merchants  Faster checkout  Ability to send directed marketing messages  Reduced transaction costs and fraud liability  Increased customer satisfaction and loyalty through offers

and reward programs

 Consumers  Faster checkout  Security  Convenience

27

Value proposition and challenges  High cost for merchants  POS terminal updates or replacement  New systems may need development

 Adoption by consumers  Consumers averse to change  No incentive to use contactless payment card (even if they

have such a card)

 What is the revenue model?  More players in the revenue food chain

 Untested technology

28

Critical issues – privacy and control  Whose customer is it?  Whose data is it?  How can I market to these customers?  How can I help others market to these customers?  Google Offers, mobile couponing  How can I use information about these customers?  Geo-location, etc  Who controls collection?

 Who controls communications with customers?  Who safeguards the customer data? (liability for breach)

29

Critical issues – financial services  Who powers the payments and how?

 What payment instruments? Debit instruments

subject to possible Fed rate cap  What authority? (bank or money transmitter)  How does the financial institution meet its compliance obligations?  If the MNO wants control – how does it comply with financial services laws and regulations?

30

Critical issues – technology and operations  How should the solution be implemented?  Whose intellectual property is used?  Is the business model financial institution- or mobile

operator-centric?  Who manages the secure element and applications on the secure element?  Will the application be open or closed (or somewhere in the middle?)  Consumer choice and ubiquity

31

Critical issues - economics  What are some possible revenue models?  Incremental revenue attributable to NFC  Pay-as-you-go model  MNO or TSM obtains revenue from application issuers for personalization and provisioning

 Landlord-tenant model  MNO obtains revenue from charging application issuer ―rent‖ for space of secure element

 Interchange and transaction revenue  Banks obtain revenue through current interchange process no matter which business model is chosen, however, interchange usage fee must be shared with more parties  MNO obtains revenue from increased data usage
