slot reader
A slot reader, slot scanner, is a stationary peripheral device used to read customer cards, insurance cards, bank cards, credit cards and other cards with magnetic stripes or bar codes.
For reading, the cardboard cards or plastic cards are pulled through a slot. The swiping can be done in both directions. During swiping, the data is scanned by the scanner from the bar code or magnetic stripe. A visual indicator shows whether all the data has been read correctly.
The slot or magnetic stripe reader can be integrated into the terminal keyboard, the ATM or the point of sale( POS).
