Yes, on Oahu paying by debit or credit card now always has fees whether at a kiosk, satellite city hall or online website. I have not checked other counties. Mailing a check is just the price of the stamp 63¢ & envelope Paying cash/check in-person during business hours does not have any additional costs, but maybe you pay an ATM fee to get cash. On Oahu: Mail Motor Vehicle Registration Renewal notice in envelope with first class stamp (63¢) to: Department of Customer Services Division of Motor Vehicle, Licensing and Permits P.O. Box 30320 Honolulu, Hawaii 96820-0320 with check or money order made payable to “City and County of Honolulu.” Kiosk 2.5% credit/debit card fee + $4 transaction fee Satellite city hall locations 2.35% service fee for credit/debit card (VISA, MasterCard, or Discover). No fee to pay in cash or check Online 2.35% fee 2-6 weeks before expiration: Go to http://www12.honolulu.gov/mvrreg/ Enter Last 4 digits of VIN Enter license plate number Follow any additional instructions. Confirm that all of your information is correct. Pay renewal fee and service charge (Visa, Discover, & MasterCard only). Print/save your receipt. New registration materials will be mailed within 10 working days for online renewal. Make sure to allow for plenty of time to receive your registration materials, because you can be ticketed if you do not have your valid registration. Edited to add: It's a bit stressful not knowing for weeks if registration was lost in the mail after purchased online or if the check you mail was lost in the mail or did not get processed correctly. Also a hassle if the registration was not received in the mail after 2 weeks from paying online or in the mail. It might be worth it to pay the fees and the kiosk to not work about the mail.
