NEW YORK (PIX11) — The impending subway fare hike started three weeks early for some commuters on Monday.

The MTA reported some riders who used the OMNY system were mistakenly charged $2.90 instead of $2.75.

The glitch was caused by a testing error from the company that operates the contactless payment machines.

The MTA said the issue was resolved by 9 a.m., and anyone who was overcharged will be reimbursed the 15 cents.

Starting on Aug. 20, all single rides on the bus or subway will cost New Yorkers $2.90.
