What type of devices are typically involved in M-commerce?

M-commerce, or mobile commerce, primarily involves transactions conducted via mobile devices. Cell phones and PDAs (Personal Digital Assistants) are designed specifically to support wireless communication and internet access, making them ideal for mobile commerce activities such as online shopping, banking, and payment processing.

These devices offer portability, convenience, and various applications that facilitate seamless transactions anytime and anywhere, which is the essence of mobile commerce. The capabilities of these devices include mobile apps and responsive websites that enhance the user experience for mobile shoppers.

While other devices such as desktop computers and smart TVs can facilitate online shopping, they do not fit the "mobile" aspect central to M-commerce. Wearable technology can also play a role in M-commerce, but cell phones and PDAs are the primary and most widely used devices in this context, making them the most appropriate choice for this question.
