The  is a player for playing Videocards. It is similar to the models.

Types

 * Model 1 - Was first released by with the launch of the Videocard in 2001. It lacks a backlight (though a light called the Videocard Light Switch was available to make up for the lack of a backlight) and takes 2 AA batteries (free  batteries were given away with earlier units).
 * Model 2 - Was released in 2003. It has major upgrades: it has a backlight, fast forward and rewind, and AV cable ports in the back of the unit.
 * Jr. - Was released by in association with SanDisk the same year as Model 2. It is a variation of Model 2 designed for preschoolers. The Videocard releases marketed for this model are flexible and are coated to taste bitter. This was done to: 1. prevent small children from bending—and thus breaking—the cards, and 2. prevent said small children from swallowing the cards, as the model is aimed at them.
 * Model 3 - Was designed and released by Theorysonic as their own version of the MobilePlayer in 2002, and released by SanDisk as the Model 3 MobilePlayer in 2005. It is backlit and has a larger screen, plus it comes with a charging port for an alternative power supply.
 * Model 4 - Was released by SanDisk in 2006. It is smaller than the other three models and has a OLED screen instead of a backlighted screen. The AV ports were removed from this model.

Accessories

 * The VideoCard Light Switch: A light accessory made for Model 1 as SanDisk rushed the model's development and forgot to put in a backlight. The Light Switch hooks up to the headphone jack and taps into the battery area via a radio frequency thanks to a miniature transmitter located in the Light Switch (when the Light Switch is turned on, three DTMF tones (going 1, 5, and 0) respectively are heard coming from a special speaker on the Light Switch, this is the VideoCard MobilePlayer Model 1 receiving the signal from the Light Switch). Starting with Model 2, all MobilePlayer models had an internal backlight, making the creation of versions of the light for them unnecessary.
