Hi. Can use up to 20 dollar bill or credit/debit card. Machine gives change for small bills & half quarters & half $1.00 tokens for large bills & cards. It's actually nice to use tokens otherwise you"re shoving $3-$4 worth of quarters into slot. OK it sounds expensive but machines are big! There are some smaller one's across from back wall that mgmt runs specials on but I liked the big ones. Also if you go frequently & sign in each time after 5 x you get a free wash. A coupon is mailed out that works in change machine.
If you put singles in you get quarters
Debit-credit card / bill-cash reader dispenses tokens ($1 value) and quarters.
They have a debit reader that gives you a mix of couns and tokens.
