What is the primary purpose of embossing on an access card?

The primary purpose of embossing on an access card is to place raised data for reading. This technique involves creating raised letters and numbers on the surface of the card, which allows for easy tactile verification. Individuals can feel the embossed characters, making it convenient to confirm identity or access levels without needing to visually inspect the card. Embossing is especially beneficial in situations where quick identification is necessary, such as at security checkpoints or access-controlled areas.

Embossing also adds a layer of authenticity and security to the card, as it is more difficult to forge than standard printed text. While graphic design and aesthetic enhancement may be considerations in the overall design of an access card, the primary functional aspect of embossing is its role in ensuring that critical data can be reliably and efficiently read by humans or card readers designed to detect raised information.
