Three day travel pass
Hello, I would like to buy a three-day travel pass for metro in Shanghai.
1) Is it possible to buy it after landing at Shanghai Hongqiao airport? Is it available on the airport or at the metro station? Is it possible to buy it with VISA/Mastercard or with Alipay?
2) Is this a physical card? While I am approaching a gate I just scan it and the gate open?
3) Is the validity period of the pass count from the moment of buying it or after first time I use it? I'm planning on staying in Shanghai for 4 days. I thought the most beneficial way is to buy a 3-day travel pass and a 1-day travel pass and I am wondering if I can buy them at one time and just use the one-day pass after the expire date of the three-day pass or is it necessary to buy the second pass later?
