The MiriPay™ applet is the easiest, most secure way to make cell phone-based purchases today. With a "click and buy" interface, a mobile online purchase can be made in four easy steps.

Touch the MiriPay™ logo and then enter your security code to activate the payment applet.
Select an expiration timeframe for the transaction and then press the "Go" button to create a MiriPay virtual number. The transaction expiration date and Miri ID will be embedded in the MiriPay virtual number that is generated.
Press the "Use" button to make the payment to the merchant. The merchant submits the payment for approval like any other credit/debit card payment.
The color of the MiriPay number will turn red indicating that it has been used and is no longer available. Press "New" to start the process all over again.
