suppliers have to work together to accomplish inter- and intra-regional interoperability, par-
ticularly when there is a significant generation gap in the technologies employed.
1.4 Interoperability Beyond Transit
The financial services industry anticipates two types of interoperability opportunities with
transportation participants:
· "Real Estate" Sharing on the Card--There are two models. In each model participants do not
interact. In one model, an ATM or credit card embeds a chip containing the transportation
application. In the other, an ATM or credit card has the transit application resident with the
credit and debit card data on the same chip. Table 1 shows the relationship of a shared-chip
architecture.
· Card Functionality Sharing--This occurs when the transit application can be used to pay for
services beyond transportation or a non-transit payment product can be used to pay for a ride.
Table 2 shows the relationship of a shared application structure.
The interoperability elements discussed in this report also apply to interoperability with non-
transportation participants. An agreement between the participants must first be established.
Once an agreement is established, the interoperable technology solution can be identified and a
clear set of business rules developed that, at a minimum, define the following:
· Technology requirements,
· Processes for system operation,
