Over the course of the last year, schools have come under fire for putting unhealthy options in on-campus vending machines, prompting some states to ban junk food and others to try and work out healthy snack plans with the food companies. As a result, many schools have been left without snack and soda vending machines. This isn't necessarily a bad thing, but you can bet that at least some of the kids are disappointed.

To try and take up some of the slack that the departure of unhealthier fare left, the Dole fruit company has taken its own initiative to start a program "that will put vending machines selling healthy food products into schools." Dole's machines will stock fruit, fruit bowls, salads, sandwich wraps and milk. The salads and sandwiches will be prepared fresh at a nearby (or possibly on-campus, if available) cafeteria.

The machines will be launched in 15 schools in four states - Mesa, Arizona; Denver, Colorado; Shawnee Mission, Kansas; Corpus Christie, Texas and Conroe, Texas - in February, but the company has high hopes and is already working on plans for expansion.

It looks like you won't have to fish for change to get that bag of Flamin' Hot Cheetos and Diet Coke for lunch out of the vending machine. Thanks to a partnership between MasterCard and Coca-Cola, vending machines are now taking all forms of payment, including credit and debit cards. In Philadelphia, 1,000 of these card-swiping vending machines have been rolled out.

At first, it sounds great. "Wow! I can use my credit card! I don't have to carry change anymore!" But, as the article states, the concept "inevitably raises questions about when a convenience might become an enabler, encouraging consumers to drink more soda or buy more candy, while spending money they don't necessarily have" and health professionals are worried.

Now, I am all for convenience when it comes to shopping, and a credit card certainly makes it easier to make a purchase. However, if you don't have seventy-five cents, do you really need to take out your credit card and charge that tiny amount? If you don't have the change, skip the snack and wait for a real meal.
