What Is a Memory Card Adapter?

By Cameron Easey

A memory card adapter has many uses in order for data that is contained on it to be transferred to a computer or other device. Typically, an adapter converts a specific type of memory card into another format or size that is required to read the data.


There are various types of memory card adapters available. Many cameras use their own type of memory card, such as those from Sony. An adapter is usually required to convert the card into a format that can be used with a memory card reader. One of the most common types of formats for a memory card adapter is SD, or Secure Digital.

Size Issues

Many memory cards are not the proper size to be read by some of the readers that are available. One type of memory card, a microSD, is very small and is used in many types of cell phones for additional storage. This card requires an adapter to convert it into a bigger size that can be inserted into a memory card reader.


A memory card adapter can connect directly into a USB port on a computer. This type of adapter can support different types and sizes of memory cards. One type of USB adapter is the MobileMate from SanDisk (see Resources). The MobileMate is capable or supporting SD, microSD, miniSD and MMCmobile memory cards. A USB adapter functions just like a portable flash drive.


A memory card adapter is used to transfer data from one place to another. A USB adapter can be taken from one computer to another to transfer data. A memory card adapter can also be used as a substitute for a specific type of memory card. This is because a memory card adapter can be used to change the size and type of one kind of card into another.


The prices of memory card adapters can vary depending on the type of adapter that needs to be purchased. Some adapters are included free when a memory card reader is purchased. Depending on the type of adapter that is needed, prices can range from $10 to as much as $30 or more.
