How much is each transaction worth?

Marion County Bank will donate up to 10% of their interchange income for transactions that require a signed sales receipt (including internet transactions) and up to 10% of income will be donated for each transaction that requires a PIN (with the exception of any ATM transactions). The overall donation each school receives depends on how many customers choose that school, and how many transactions are made. The income is figured by Shazam based on the amount of card usage. The more a debit card is used, the more money the school will receive.
