I keep mine in the wallet. Though it is a bit bothersome given so that I don't forget, I bring 2 Autosweep and 2 Easytrip Cards in case I am driving main car or second car, and suddenly detour through one of the expressways (unplanned). Has happened a few times where I detoured to NLEX to get out of traffic from Novaliches/Quirino Hway/TandangSora area.

Though di pa ako nagkataon na hindi mabasa sticker sa headlight so di ko pa need hugutin yung card to show guard/personnel ng toll
The card is linked to the vehicle, so leave it inside the vehicle, bro.

I have not experienced any warping.
