To my suprise, most of these card readers act as an HID that mimics a keyboard. Simply put, you swipe a card and it types the data out that is on the magnetic strip. Also to my suprise these work out of the box on Linux & Android systems.

## Financial Cards
|
||||||
|
These follow the ISO/IEC 7813 standard which define the properties of financial transaction cards.
|
||||||
There are up to three tracks on magnetic cards known as tracks 1, 2, and 3. Track 3 is virtually unused by the major worldwide networks, and often is not even physically present on the card by virtue of a narrower magnetic stripe. Point-of-sale card readers almost always read track 1, or track 2, and sometimes both, in case one track is unreadable. The minimum cardholder account information needed to complete a transaction is present on both tracks. Track 1 has a higher bit density *(210 bits per inch vs. 75)*, is the only track that may contain alphabetic text, and hence is the only track that contains the cardholder's name.
|
|
||||||
|
|
||||||
### Track 1
|
### Track 1
|
||||||
Track 1 is written with code known as DEC SIXBIT plus odd parity.

###### Format A
|
Track 1 is written with code known as DEC SIXBIT plus odd parity.
|
||||||
Reserved for proprietary use of the card issuer
|
|
||||||
|
|
||||||
###### Format B
|
It can contain up to 79 characters.

|
|
||||||
| Service code | three characters |
|

### Track 2
|
### Track 2
|
||||||
This format was developed by the banking industry *(ABA)*. This track is written with a 5-bit scheme *(4 data bits + 1 parity)*, which allows for 16 possible characters, which are the numbers 0–9, plus the six characters : ; < = > ? . *(ASCII range 0x30 through 0x3f)*
|
|

| Expiration date | four characters in the form YYMM. |
|
|
||||||
| Service code | three digits. The first digit specifies the interchange rules, the second specifies authorization processing and the third specifies the range of services |
|
|
||||||
| Discretionary data | as in track one |
|
|
||||||
| End sentinel | one character (generally '?') |
|
|
||||||
| Longitudinal redundancy check (LRC) | it is one character and a validity character calculated from other data on the track. Most reader devices do not make the LRC available for display, but use it to verify the input internally to the device. |

### Track 3
|
||||||
|
|

#### Service Code
|
It can contain up to 107 characters *(same density as track 1 but has the same character encoding as track 2)*
|
||||||
|
|
||||||
|
Most cards do not even use a 3rd track, and is mostly un-used worldwide.
