Here are the main questions about magnetic stripe cards and their use.
MAGNETIC STRIPE CARDS
Magnetic stripe cards feature a black or coloured ferromagnetic strip on the back. The stripe can be 12.75 mm high, if it has 3 tracks, or 8.4 mm high, if it has 2 tracks. The benefits of magnetic cards primarily concern their versatility, allowing them to be used for various applications.
What are the main magnetic stripe card uses? They are widely used in the Retail industry and Large-Scale Retail distribution, as gift cards, and as magnetic stripe cards for access control:
- Magnetic stripe gift cards: gift cards with magnetic stripe allow you to gift a monetary amount to be spent within a store. They have variable duration and value.
- Secure magnetic stripe cards are for employee identification: magnetic stripe cards for employee ID are used in companies, controlling access to buildings, services, or specific areas, and allowing attendance tracking. Badges are also used within schools and universities.
- Hotel magnetic stripe cards: in hospitality facilities, magnetic stripe cards for hotel keycards regulate access to rooms and restricted areas.
- Membership cards with magnetic stripe: they are useful for identifying and recognising members in cultural associations, non-profit organisations, and sports federations.
- Gym cards: in gyms, swimming pools, and wellness centres, magnetic cards are used for member identification and access control.
Magnetic cards are compliant with the ISO 7811 standard, which defines dimensions, encoding, and coercivity. Coercivity represents the intensity of the magnetic field and is measured in Oersted (Oe).
The magnetic stripe can have a coercivity of 300, 2750, or 4000 Oe, and based on the value, it is divided into two categories:
- LoCo (low coercivity, 300 Oe), which is more subject to demagnetisation;
- HiCo (high coercivity, 2750 Oe and 4000 Oe), which offers greater resistance to magnetic fields. The higher the Oersted value, the more secure the magnetic stripe is.

Magnetic stripe card technology
The magnetic stripe consists of a PVC layer composed of resinated ferromagnetic particles: data are stored by altering the magnetic orientation of these particles. The information is read by ‘swiping’ the card with the magnetic stripe inside a magnetic stripe card reader.
Encode magnetic stripe cards
How to encode magnetic stripe cards? Magnetic stripe cards can be encoded with various categories of data, including: expiration date - for example in the case of gift cards - and programming information, such as numerical access codes, authorization levels, and operating parameters.

Custom magnetic stripe cards
Magnetic stripe cards can be made from a variety of materials, including PVC and PETG, which are resistant to high and low temperatures, chemicals, and offer excellent printability; degradable PVC and recycled PVC, which share the same technical characteristics as standard PVC but are more sustainable.
Magnetic stripes can be applied to the card using two methods: flush-on, where the stripe is inserted during the lamination process, and roll-on, where the stripe is applied subsequently. Additionally, magnetic stripe cards programming can be carried out into three tracks: ISO 1, ISO 2, and ISO 3.
At Partitalia, we offer custom magnetic stripe card printing services, including custom logo and graphic printing. Magnetic stripe card printing includes 4-colour offset, silkscreen printing, digital printing, UV spot varnish, and hot stamping. Variable data printing, such as names and numbers, is achieved through techniques like thermographic printing, laser printing, inkjet printing, and embossing.
FAQs magnetic stripe cards
What is a magnetic stripe card?
Magnetic cards feature a black or coloured ferromagnetic stripe on the back. The stripe can be 12.75 mm high, if it has 3 tracks, or 8.4 mm high, if it has 2 tracks.
How do magnetic stripe cards work?
Magnetic cards store data through a ferromagnetic strip located on the back of the card. The strip consists of a layer of PVC, containing tiny resin-coated ferromagnetic particles. The card is read by swiping it through a magnetic card reader.
What are the common uses of magnetic stripe cards?
Thanks to their versatility, magnetic stripe cards are used for multiple applications: as gift cards in Retail and Large-Scale Distribution; for employee identification in companies and student identification in schools and universities; for access control in hotels and gyms; and as membership cards in cultural associations and sports federations.
What data can be stored on a magnetic stripe card?
Magnetic stripe cards store information such as the expiration date - if used as a gift card - and programming data, e.g. numeric access codes, authorisation levels, and operating parameters.
How secure are magnetic stripe cards?
The security of magnetic stripe cards is evaluated by the coercivity, i.e. the strength of the magnetic field, which is measured in Oersted. The higher the Oersted value, the more secure the magnetic strip. The most secure magnetic cards are those with high coercivity (HiCo, 2750 Oe and 4000 Oe).
