A driver's license cannot be used as a credit card. The driver's license is not a valid identity document and cannot replace the ID card credit card. Driver's license is the abbreviation of motor vehicle driver's license, also known as "driver's license", which is a license that motor vehicle drivers need to apply for according to law. Driving a motor vehicle requires certain driving skills. Without this skill, driving a motor vehicle at will may lead to traffic accidents, and ordinary people can't drive on the road without a license. But for people who already have safe driving skills, they drive vehicles on the road, and this allowed certificate is the "driver's license". In other words, a driver's license is a kind of "license certificate". It is not legal and valid identification, so it cannot be used as a credit card.
