An electronic payments system-based vending machine is risker (where the risk is to your ability as a consumer to get a coke on demand) than the current model (coin operated vending machine) since it depends on connectivity to the payments network to function. This is easily interrupted through malice, negligence, or oversight. In my experience coin op vending machines by and large work; bill readers are hit and miss; card reading machines almost never function. (BTW not downvoting you, but your comment does inexplicably ignore coin op machines which are an existent, good solution.)

The Chip+PIN system includes an offline mode, which is especially suitable for small transactions like this. "The transaction is authorized either online and offline. For an online authorization, transactions proceed as they do today in the U.S. with magnetic stripe cards. The transaction information is sent to the issuer, along with a transaction-specific cryptogram, and the issuer either authorizes or declines the transaction. In an offline EMV transaction, the card and terminal communicate and use issuer-defined risk parameters that are set in the card to determine whether the transaction can be authorized. Offline transactions are used when terminals do not have online connectivity (e.g., at a ticket kiosk) or in countries where telecommunications costs are high." http://www.emv-connection.com/emv-faq/ http://www.emv-connection.com/emv-faq/ It's in wide use in Europe, for instance a ticket machine on a train or tram, or for low-value transactions (bus tickets, fast food), or where there's no connection (purchase on a plane -- where they will probably only accept credit cards beyond a certain amount).

In Japan, vending machines that take Pasmo and similar smart cards are pretty common. But Japan is pretty much an outlier AFAIK in its extremely widespread use of this type of technology.

  Not just in Japan, plenty of countries in Asia have offline stored-value cards that started out as train cards but can be used in many shops [commonly in convenience stores] as well (see Octopus in Hong Kong, ez-link in Singapore, EasyCard in Taiwan, Touch 'n Go in Malaysia, etc)
