What Is a Memory Card Adapter?

Updated February 21, 2017

A memory card adaptor has many uses in order for data that is contained on it to be transferred to a computer or other device. Typically, an adaptor 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 adaptors available. Many cameras use their own type of memory card, such as those from Sony. An adaptor 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 adaptor 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 adaptor to convert it into a bigger size that can be inserted into a memory card reader.


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


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


The prices of memory card adaptors can vary depending on the type of adaptor that needs to be purchased. Some adaptors are included free when a memory card reader is purchased. Depending on the type of adaptor that is needed, prices can range from £6 to as much as £19 or more.
