In what form are ID cards issued for individuals aged 21 and over?

ID cards for individuals aged 21 and over in Texas are issued in a horizontal format. This design is significant because it visually distinguishes adult identification from those issued to minors, which are typically displayed in a vertical format. The horizontal ID cards are easier to read and verify, especially when checking for age, as all important information can be displayed more clearly in this orientation. This standard format is widely accepted and recognized, aligning with practices used in many other states and facilitating smoother transactions in various settings where ID is required, such as bars, clubs, and financial establishments. The other shapes, such as square or rectangular formats, are not standard for ID cards, making horizontal the conventional choice for clarity and consistency in adult identification.
