Someone mentioned the use of ATM's. I searched on the internet and found this one:
https://lamassu.is/They're quite expensive ($6500) but maybe interesting for in the future.
Although, I'm not sure wether this type of ATM's do support altcoins like guldencoin?
There was a user that contacted Lamassu directly and the prices are a bit different...
" lead time for ATMs is 8 weeks. The cost is $1,800 per ATM and we can set it up to dispense iXcoins as well as Bitcoins [and any other alts as well]"
How cool would that be, an ATM like that at those Subway stores? Can we fund that?
