It's gonna be a problem on the TTC, because the readers in vehicles are mounted very low (For accessibility) so if you lean against the reader with your wallet in your pocket, BAM, you're gonna get charged.
I've had just my phone in my pocket and when close to a reader, the phone dings and activates the Wallet because it sensed a reader nearby (even though it can't be used).
Gonna need RFID wallets more than ever, for those who ride regularly.
The new readers require that you take the card out of your wallet because people generally carry multiple RFID enabled cards these days. It won’t read it if it receives multiple signals.
But really, out of courtesy for others, you should not be leaning on the readers or even standing in the doorway.
