Thx EM! Been rather busy at work as well, not much time to do up most of them..
Hi Kazeeee
You need to call the bank to issue you a PIN number. It will take some time before they mail you the PIN, which often times can be changed at the ATM ( at least for UOB ). I do not know about debit cards.
There are several gas stations in Iceland, N1 having the widest coverage. N1 gas booths allow credit cards that have PINS that are more than 4 digits. Icelandic credit card PINS are only 4 digits. The other companies such as Orkan has credit booths that ONLY ALLOW 4 digit PIN entry on the interface ( which meant my 5 PIN UOB credit card or other 6 PIN US issued credit cards are rendered unusable )
All the pink Orkan gas stations we saw appeared unmanned. The gas station at Kef airport car park is an Orkan station. * When we returned the rental car, we had to tell the car rental company to charge our credit card backend to top up to full tank because we cannot operate the Orkan pump..
All the green Orlis gas stations we passed by had pump station / attendant.
Most of the N1 gas stations we saw were unmanned except the large ones in Reykjavik
For most of the parts, N1 credit card interface was in Icelandic except the newer or larger Reykjavik ones ( but with abit of guessing you will know how to do it ) - also there are like 3 versions of pump interface hah. During the credit card entry you will be requested to enter the amount you wish to pump. So if you indicated 5000 isk on the system, and you only pumped 4000 isk, only 4000 isk will be deducted. The pump knows the end of the pump when you rest the pump head back into position. So it is highly unlikely someone next gets to use up your extra credits since transaction would have ended. For many terminals, one credit card interface serves two pumps, so you will have to indicate which pump number you are paying for.
Some of the manned stations actually open till 11+ pm, but please check to be sure.
I did not need to get any prepaid cards during my trip, but I know N1 sells prepaid cards with various value denominations. Apparently Olis stations do as well ( but there was one attendant in Selfoss branch that told me they/Olis do not sell them ) We bought an Icelandic driving map from Borders which indicated fuel station ( but did not tell us which gas company ). you can refer to this page as well, although I am not sure how up to date:
