At the RetailTech 2010 exhibition in Japan, a new Coca Cola vending machine was demonstrated which uses Hitachi’s finger vein authentication technology to dispense Coke bottles. This biometric system employs finger pulse recognition to authenticate a user after which his credit card or account is automatically debited. The technology may be safer and more convenient than conventional e-money systems since it does not need any passwords or IDs. The users can also register their postal and email addresses to claim free samples directly through the digital signage built into the vending machine.
