iPark provides merchants with a simple mechanism for providing parking endorsements to
their best customers for both on-street and off-street parking. A participating merchant
signs up for a block of endorsements, each with a short unique key, through the iPark
website. The merchant rewards select customers with an electronic parking endorsement credit
that is triggered through a unique key. The customer enters the key into his/her cell phone,
via an Endorsement command. This will automatically debit the merchant's endorsement pool and
credit the customer's parking account.
