On my travels, I've been to my fair share of airports and, sometimes, I see or use things that are so brilliant that I want them everywhere. I've listed these under the airports where I discovered them (they might be available at other places but I only know what I know).
Traveller Box (Milan)
I saw this at Milan airport and it blew my mind. Like an ATM contraption but you put in your foreign money that you are never going to use again and it deposits it in your Paypal account. Well, I deposited it in my Paypal account. There are other options like iTunes and Amazon (I think).
I was a bit sceptical. I mean, it'd be a brilliant scam to set something like that up at the airport and just collect money from unsuspecting travellers. But nope, no scam. I put in my coins and a 5 euro note and keyed in my email address. Sure enough, not long after, I got an email from them saying the money was ready to transfer.
Being super cautious about using public wifi (as you should be), I waited until I could safely check it all out. Yep, all clear.
The only bad side was the poor UNICEF coin collection getting less love.
Taxi Vouchers (Kuala Lumpur)
I have a fear of being ripped off by cab drivers. After all, I lived in Melbourne for years and the cab drivers there are as dodgy as fuck. So, I'll use complicated systems of public transport and lug all my shit rather than get a cab.
When I arrived in Kuala Lumpur though, I noticed there were counters selling vouchers for taxis. Actually, it's the only way to get a taxi from the airport.
It's brilliant. You tell them your address and pay them the cab fare. You get the voucher with your address written for the cab driver to follow (no awkward language stuff although the driver I had was pretty much fluent) and no getting scammed on the fare.
Note: I also saw this at Dubrovnik airport but there was no one manning the counter so it was kinda useless.
Capsule Hotels (Kuala Lumpur)
Another things I've been raving about to everyone who will listen. Capsule hotels are airports are freaken awesome. I've been to Japan so many times and never stayed at a capsule hotel (many of them are men only and often they aren't that cheap) but, needing a kip at the airport, I took the opportunity.
Even a short, three hour naps makes the world of difference when you are tired and cranky. Seriously, I reckon half the scams and crimes committed on travellers happen not because people are stupid but because they are over-tired from flights etc and not thinking straight.
I think I paid around $20 for 3 hours, can't really remember exact details now, and got a warm shower and a bed with crisp, white sheets.
Note: I know Haneda airport has capsule beds.
Other note: KL also has an awesome transit hotel for when you have long stopovers on your Air Asia flight.
Takkyubin - Delivery Service (Tokyo)
When you get to the airport in Japan, you can go to a counter and get all your shit delivered to your hotel or accommodation. No trying to deal with bulky suitcases on the train, no being a douchebag with a huge backpack on your back. You can travel light and carefree as though you have no luggage at all.
I'm not 100% behind this service because the guy working on the counter at Narita was incredibly rude when I arrived. I filled out the address in English. FFS, I'd been flying for hours and I wasn't even going to try writing kanji which would probably be wrong anyway. If they have the postcode and other numbers for your Japanese address, they can find the place. He was just being a pig.
The other downside is that the delivery is overnight. Not so bad if you are staying at a hotel but otherwise you either have to wait around for delivery or risk missing it (they do leave a card with an English call line so you can arrange redelivery).
Have you ever seen something awesome at an airport and wished you could get it every time you flew?
