Contactless payment works by using radio-frequency identification (RFID) or near-field communication (NFC) technology to enable secure transactions between a contactless card or mobile device and a contactless-enabled payment terminal. When a contactless card or device is tapped or waved near the terminal, the necessary payment information is transmitted wirelessly, allowing for a quick and convenient transaction without the need to physically swipe or insert a card. Contactless payment is typically used for small purchases and offers a faster and more hygienic alternative to traditional payment methods. **

Contactless electric cars are vehicles that can be charged wirelessly, without the need for physical cables or plugs. This technology uses electromagnetic fields to transfer energy from a charging pad on the ground to a receiver on the vehicle, allowing for convenient and efficient charging. Contactless electric cars are a promising development in the electric vehicle industry, as they offer a more seamless and user-friendly charging experience for drivers. This technology has the potential to make electric vehicles even more accessible and convenient for consumers. **

A contactless key is a type of key that uses radio frequency identification (RFID) or near-field communication (NFC) technology to allow access to a building or vehicle without the need for physical contact. This type of key typically comes in the form of a card or fob that can be waved near a reader to unlock doors or start a vehicle. Contactless keys are convenient and provide a hands-free way of accessing secured areas or operating vehicles. **

The opposite of contactless is "contact." Contactless refers to a method of payment or interaction that does not require physical touch, while contact involves physical touch or interaction. For example, a contactless payment is made by waving a card or using a mobile device, while a contact payment involves inserting a card or using cash and physically touching a payment terminal. **

Yes, contactless charging technology is expected to be expanded in the near future. As the demand for convenient and efficient charging solutions continues to grow, companies are investing in the development and implementation of contactless charging technology for a wide range of devices, including smartphones, electric vehicles, and wearables. With ongoing advancements in wireless power transfer and the increasing adoption of contactless charging standards, it is likely that we will see expanded use of this technology in various industries in the coming years. **

No, it is not safe to continue driving with worn brake pads and brake discs. Worn brake pads and discs can reduce the effectiveness of the braking system, leading to longer stopping distances and potentially causing a dangerous situation on the road. It is important to replace worn brake pads and discs promptly to ensure the safety of yourself and others on the road. **

Yes, a TÜV inspector does check brake pads and brake discs during a vehicle inspection. The inspector will visually inspect the brake pads and discs for wear and damage, and may also measure the thickness of the brake pads and the condition of the brake discs. This is an important part of the inspection to ensure that the vehicle's braking system is in good working condition and meets safety standards. If any issues are found with the brake pads or discs, the inspector will advise the vehicle owner to have them replaced. **

The need to replace brake discs and brake pads depends on their condition. If the brake pads are worn down to a thickness of 3mm or less, or if the brake discs are warped, scored, or have a thickness below the manufacturer's recommended minimum, then they should be replaced. Additionally, if there are any signs of brake pulsation, squealing, or grinding, it may indicate the need for replacement. It is important to have a professional mechanic inspect the brakes to determine if replacement is necessary for safe and efficient braking. **
