Some possible reasons why you are not getting the on-arrival text include: You may not have driven under the RFID reader – these are located in the awning above the gas pumps at the station. If you are at the gas station but have not pulled up to a pump yet, you may not be close enough to the reader. If your E-ZPass transponder is older than 10 years it may need to be replaced, as the battery life may be at its end. Toll transponders may begin to weaken at that point. To get a new toll transponder, you should contact the toll agency’s customer service center’s number usually visible on the transponder itself. We can also send you a non-toll PayByCar smart-tag if you email us at support@mypaybycar.com including your current tag number or smartphone number and a mailing address where you receive mail. Your transponder may be mounted to your windshield incorrectly, or your windshield has special features that make it difficult to scan your transponder. Click here for a list of vehicles with these features and suggestions for alternative transponder placement. You may have entered your transponder number incorrectly when you added it to your PayByCar profile. There may be a delay due to cellular network congestion in the area. We may be doing system maintenance, which typically occurs for a short period of time between 2am-4am EST. If we are experiencing an unplanned system outage (for example, a power outage in the area), we will send an email to alert all PayByCar members who may be affected. If none of these reasons apply, contact us so we can offer assistance.
