Took me 11 days to figure out why my hostel key card kept dying in Lisbon
Kept it next to my phone in the same pocket for 4 days straight before a front desk guy at Home Lisbon Hostel asked to see my wallet. The magnet in my phone case was erasing the card strip every single time. Bought a $3 rfid sleeve at a tram stop kiosk and never had a problem again. Anyone else wreck a key card this way or am I the only one?
