At Macau airport yesterday – mobile phone sim cards for sale through this vending machine. Put in your payment and out comes the card, ready to use.
Who needs retailers?
This unit reminded me of the instant scratch lottery tickets I saw in supermarkets in the US being sold from vending machines as a means of using your loose change.
From a legal point of view the use of such a machine probably makes tracking sim cards easier. That is, if the machine uses video survalance and there are the processes in place to track cards back to the vending machine.
