Last week we featured solar chargers in our boring product of the week series. This week we have another peripheral as our boring product of the week; the memory card reader.
Useful but Boring
Memory card readers are very useful if you don’t like to carry all those clunky USB cables that use different interfaces for digital cameras, camcorders, mobile phones or MP3 players. With the memory card reader you can transfer your data from your memory card to your PC just as you transfer from a USB flash drive.
Memory card reader
A memory card reader typically has a USB interface for accessing the data on a memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC). Though from the name of the device it only looks like that a memory card reader can only ‘read’ a memory card’s flash memory, most card readers also offer a write capability as well.
Together with the memory card, it can also function as a USB flash drive. Some modern printers and most notebooks and netbooks now have a built-in memory card reader.
Multi card reader
A multi card reader is a type of memory card reader that is used for communication with more than one type of flash memory card. Multi card readers do not have any built-in memory capacity, but are able to accept multiple types and brands of memory cards.
The number of compatible memory cards varies from reader to reader and can include more than 80 different types. The number of different memory cards that a multi card reader can accept is expressed as X-in-1, with X being the number of memory cards accepted, such as a 35-in-1 memory card reader.
Categories of memory card reader
There are three categories of memory card readers sorted by the type and quantity of the card slots: single card reader (e.g. 1x SD-only), multi card reader (e.g. 9-in-1) and series card reader (e.g. 4x SD only).
