JP Morgan Chase has begun testing a $5 fee for non-customers using its cash machines.
The bank is trialling the $5 charge in Illinois while users in Texas face a $4 cost. Chase has around 3600 ATMs in the two states.
With many US banks also charging customers for using cash machines outside of their network, withdrawals could cost some users more than $8.
With the Dodd-Frank law cutting off some revenue streams, banks are looking to up the amount they make from ATM fees, estimated to be over $7 billion last year, according to the Wall Street Journal.
HSBC has begun charging non-customers $3 a withdrawal while TD Bank has introduced a $2 fee for customers using other machines.
JPMorgan has issued a statement saying banks "created a network of 9,100 ATMs for the convenience and free use by our customers. It is appropriate to charge non-customers a fee."
