Protective shells designed specifically for the iPhone 13 Pro Max often incorporate an integrated compartment or slot. This feature allows users to conveniently store credit cards, identification, or other similar small, flat items alongside their mobile device. A common example is a case with a rear-mounted pocket securely holding one or more cards, accessible without removing the phone from the case.
The integration of card storage within a phone case provides enhanced convenience and streamlines everyday carry. This design reduces the need to carry a separate wallet, minimizing bulk and consolidating essential items. Historically, this type of case evolved from simpler protective covers to meet consumer demand for greater functionality and portability in mobile accessories.
