Which process involves placing raised data on an access card?

Embossing is the correct choice for the process of placing raised data on an access card. This technique involves creating a three-dimensional effect on the surface of the card, where specific information, such as the cardholder's name and card number, is physically raised above the card's background. This raised lettering is not only a feature for aesthetic appeal but also serves practical purposes, primarily for tactile identification, which can be especially useful for visually impaired individuals.

Additionally, embossing adds a layer of security since it makes the card more difficult to duplicate compared to other printing methods. The raised characters are an integral part of traditional card manufacturing, especially in payment and identification cards, ensuring that the information is durable and less likely to wear off over time.

The other processes, like etching, printing, and stamping, serve different functions and do not create raised characters. Etching is typically a method that involves engraving or cutting into the surface, effectively creating a recessed design. Printing is a flat application of ink or toner on the card’s surface, while stamping usually refers to the application of a design or text through pressure, often resulting in a flat or indented surface.
