They may just consolidate all the charges to reduce credit card processing fees. IIRC, most card providers have a flat + percentage fee structure. I would imagine if you’re big enough, you may be able to negotiate something different?Update: Ah, I just read this, "A charge will appear on your credit card statement or in your bank account. This charge may take a few days to appear and multiple trips may be combined into one or more charges."
It’s very different from OMNY, where each individual tap is registered fairly quickly with the card provider.
