Re: voucher - Token
Some Hotspot locations have found a way to charge extra for the WIFI use. The local router requires a Voucher Token ( yes you buy time) to pass thru the modem. It usually uses the MAC address of the device wanting access. It is similar to the old and still used method of getting access to some Airport services and other for a fee WIFI systems but your given the access codes..
Bottom line is they wanted your MAC address. Safe, questionable. I'm not sure how much access they have to your phone data once you are connected.

3.Tap Wi-Fi followed by Advanced
4.Tap the Diagnostic Information bar and select Device Information
5.The MAC address appears under Physical Address
