BelMarduk asked Doesn't everybody put money in vending machines? Is junk food free in other countries

For my part, I took CapKiwi'squestion to be a refrence to the latest generation of vending machines that are starting to pop up here in NZ. These new machines are operated by cards, either credit cards or debit (POS) cards. Some use rechargeable swipe cards which come in set values and have the appropriate sum deducted from their memory after each use. The more I waffle on about these new vending machines, the less likely it seems to me that they were what CapK had in mind. Kindly ignore the above babblings.
