Reduced environmental impact in hospitality /Global/Sustainability/photos/Red%20environmental%20impact%20Hosp%20524x224.jpg The environmental impact of electronic locks and in-room safes for hotels comes from the batteries that power them and the plastic keycards used to open them. ASSA ABLOY Global Solutions has optimized electronics in these products to reduce the energy consumption and expand the lifespan of the batteries. VingCard’s Signature RFID lock provides the customer with sustainable options. RFID carriers such as key fobs or bracelets – which are returned to the hotel as the guest checks out – and low-cost paper RFID keycards are two examples. Using NFC (Near Field Communication) technology allows the locks to communicate with compatible cell phones. Therefore, once NFC is extensively deployed by mobile phone suppliers and operators, hotels may further reduce – or even eliminate – the need for keycards.
