What is magnetic stripe encoding?

Magnetic stripe encoding is a way that data can be added to an ID card and then read by a device which then decodes that data into a readable format. Data is stored on a magnetic stripe as a series of positive and negative stripe fields. Typically, three different tracks exist which hold a specific number of characters. Magnetic encoding also allows many different types of data to be stored. Many forms of ID software will allow the encoding of ID cards. However, it is essential to check this functionality before purchasing.

What types of magnetic stripes exist?

There are two main types of magnetic stripe encoding. And these are called HiCo (which stands for high coercivity) and LoCo.

The main difference between these two types is that HiCo cards are highly durable and only encoded once. They can last for long periods of time and with extended use. Contrastingly, LoCo encoded cards are more for temporary purposes that can easily be re-encoded. As such, they are frequently used for applications such as public transport and hotels.

The amount of energy that each card uses for the encoding process is another way they can be referred to. HiCo cards are more difficult to encode than LoCo ones. The energy that is used to re-encode both types of card is measured in Oersteads (Oe).

Both cards can be identified by their colour. ID cards containing a HiCo stripe will appear almost black in colour. Whereas LoCo stripes appear brown.

How do I encode a magnetic stripe card?

In order to produce an ID card encoded with a magnetic stripe, a number of items will be needed. Such as:

  • Magnetic stripe cardstock
  • ID card printer with encoding module
  • ID software with encoding functionality

In order to read data that has been encoded to the card, a number of additional items will be needed as well. Such as:

  • ID card stock containing magnetic stripes
  • Magnetic stripe card reader to read card data
  • Software to interpret data stored on the card
What are common uses of magnetic stripe cards?

Many different industries make use of magnetic stripe cards. However, they appear to be heavily used in libraries, for gift cards, tracking time and attendance and access control to buildings.

Are there any magnetic encoding options for ID printers in the ZXP 3 single-sided range?

Yes. We offer six single-sided ID card printers within the ZXP 3 range that also have magnetic encoding functionality. For entry level purposes, we stock a basic device that contains a magnetic encoder. However, we do also offer advanced models as well. To learn more, click the links below.
