Singapore expat part 3: unified payment system across transport

Just like Hong Kong (Octopus), Seoul (T-Money) and London (Oyster), Singapore has a public transport card (Ez-Link). Like HK and Seoul, you can use this card for small payments in 7/11 alike shops.

This payment card works on all transport modes. Bus. MRT (metro). No matter who operates it.

Sadly it doesn’t work on taxis though.

Nonetheless. With a bunch of different players (SMRT, SBS, any other? But the same is true for London — and they have more players on the market) they have one simple unified payment system (and prices are the same no matter who is operating).

Why is this not possible in Belgium? Don’t get me started on MOBIB.  “In order to travel validly on the networks of the various operators, you will need to store a valid transport tickets on your MOBIB card for each of the mobility operators you intend to travel with.” That’s a joke.

EVA and WiFi

So I am flying EVA from SIN – TPE – JFK and back. For the first time I also went to the dark side (16hrs was too long to be locked up with just my mind) and got onboard WiFi.

This seems to come with unlimited data for ~20USD for 24hrs. I manage to stream Google Music just fine.

I totally went Matrix mode during the flight. While the flight is half empty I am wondering if they think I am haxoring it now.

EVA uses T-Mobile Germany as carrier.

Public IP routes to a German IP (and Google redirects to Google.de).

Not very sure what’s witchery is going on here though.

There seems to be a transparant Squid/3.4.6 caching proxy running:
