A credit card that only works when it hears its owner’s voice has been developed by US scientists. Researchers hope that the【B1】______, which comes with a【B2】______voice recognition chip and microphone, will be a weapon in the battle against credit card【B3】______. Even if thieves know a card’s【B4】______and personal identification number, they will still have to copy the owner’s voice accurately. The trial-card was created by scientists at Beecard, in California US. The first【B5】______ is three times as thick as a normal credit card. But researchers believe smaller chips will allow the card to slim down to a more【B6】______ size. The card is apparently the first to put a voice recognition chip, a microphone, speaker and a【B7】______into a credit card. To use the card, the owner first presses a button, and hears the【B8】______: say your password. If the password is correct and spoken by the right person, the card【B9】______an identification signal which is【B10】______by a computer connected to the Internet. Researchers hope to get the card to handle ten transactions per day for two years before its non-replaceable battery runs out. [br] 【B4】
