A few years ago, after attending a banquet in a building, my car could not get out of the parking area, because I did not have e-Money, while the e-wallet app was on the other mobile phone that was left at home. The parking lot was very quiet, only my car had not come out, the clock showed almost midnight, I chatted with the parking attendant, looking for a solution, finally I remembered, having a Flazz card (for public transportation), after being tested by the parking attendant it turned out to be connected so that finally I could get out of the parking area and go home, since then I always carry e-money in my wallet.
