Swipe reader
A swipe reader is a device that can be used to read cards with a magnetic strip , such as Eurocheque cards . You pull the card through a deep groove in the device. Successful reading of a card is often indicated optically and acoustically.
Applications
Computer accessories
The reader is connected to a computer via the serial interface or via USB . There are also keyboards that can read magnetic cards; the data is sent to the computer as keystrokes as if it had been entered using the alphanumeric keyboard. Another variant are devices that are looped into the connection cable of the keyboard. In addition to the swipe reader as a computer accessory, it can also be found as an integrated assembly in other devices.
Door opener
For example, the bank card functions as a door opener to the anteroom of the bank in order to grant access to the ATM. It is not known to what extent the bank checks the data. Large hotels also use swipe readers as a lock replacement for their customers.
Time tracking
Time recording systems often use a magnetic stripe card to identify employees.
EC cash
Readers for EC cards also usually have a swipe reader.
Alternatives
The only alternative to reading magnetic stripe cards is the self-retracting device. The card has to be inserted manually into a corresponding opening, motors detect this and ensure a constant reading speed. After the data has been processed, the card may be issued again. This method is particularly used with paper magnetic stripe cards, where the material is not stiff enough for manual swiping. It can also be used to decide whether or not to retain the card. (Example: swimming pool , ATM )
