i-Zoom

[3] The Indiana Toll Road and the ISTHA entered into a reciprocal agreement whereby holders of either the i-Zoom or I-Pass receive a discount on tolls in either state, as well as E-ZPass users,[citation needed] and it is likewise the case between the ITR and Ohio Turnpike Commission.

About 70 percent of all electronic transactions on the ITR are done with I-PASS transponders, according to Illinois Tollway Authority figures.

[7] The 3¢ surcharge, rather, was a business decision by ITR Concession Company, the private company that operates the Indiana Toll Road, to recoup money lost as a result of the Illinois Tollway billing the ITRCC for a variety of customer service costs and the uneven amount of electronic transactions in the two states.

[5][7] As of 2012[update], while the ITR encouraged users to either purchase an E-ZPass ITR transponder or to move their business from the I-Pass system, the cost of a transponder was $10, with that price (or $8 of it if bought via retail) immediately credited as a starting balance for the tag.

Due to the low price and pre-paid deposit amount, Indiana's implementation is the lowest-priced transponder currently in the E-ZPass system.
