You can now go CharlieCard-free on the MBTA. The new “Tap to Ride” system lets riders use credit cards, phones and even smartwatches to directly pay fares on buses and subways. Here are some tips to ensure your first ride goes smoothly.
Kind of odd that the system might charge multiple cards if they’re within 7 inches of the reader. Seems like as soon as it registers 1 payment it should freeze for 3-5s before allowing another one.
I think the concern is that the reader might pick up a different payment form than the one you intend on using if there are multiple in close proximity. I highly doubt it will charge multiple times, as the sort of interlock you are describing is pretty standard NFC stuff. Using the same form of payment as you make transfers is needed to make sure you aren’t charged extra.
Amazing change!
