Using the GO Train yesterday (Saturday) I noticed an odd behaviour. It worked as normal, but just after both tap-outs, I heard a distinctive beep. Both times I looked back, but it was too late to see what the display had said. The first time I just figured that it was someone right behind me, or at an adjacent machine. But the second time I was clearly the only one around.
Today looking at my account, I can see the details for the first trip there, just fine. But both the tap-in and tap-out for the second trip are missing; normally when things are missing, all transactions for a particular station that day are late ... but in this case, my earlier tap-on/tap-off for the same stations are present. Also my balance is $4.20 lower than is possible, looking at the previous trips.
The card status still says active (does this change to something if it is suspended). And there's no point contacting them until the remaining transactions show up ... perhaps it will automatically figure it out). But I think something has changed. Has anyone else seen anything similar? First time I'd used my card in 4 days.
I went as far as going through my wallet, to see if my wife's Presto card had ended up in there somehow. No ... but I did realise that I had a brand new October TTC pass; not sure if there is something in that card that's being detected when I touch my wallet (there's no other RFID devices in there, other than Presto).
