What Is Magnetic Coercivity?
Magnetic coercivity is a measure of a magnetic material’s resistance to being demagnetized. In simpler terms, it tells us how hard it is to erase or alter the data stored on a magnetic stripe.
- High coercivity (HiCo): Hard to erase or demagnetize, stores data securely, and can withstand repeated use in access or payment systems.
- Low coercivity (LoCo): Easier to encode but more susceptible to accidental erasure or magnetic interference.
Magnetic coercivity is measured in oersteds (Oe) or kilooersteds (kOe). Most LoCo magnetic stripe cards are around 300 Oe, while HiCo magnetic stripe cards are around 2750 Oe or higher. The higher the coercivity, the more resistant the card is to magnetic fields and wear, making HiCo cards the preferred choice for high-security applications.
HiCo vs LoCo Magnetic Stripe Cards
The difference between HiCo and LoCo cards is not just technical — it determines how and where the card can be used effectively. Here’s a side-by-side comparison:
| Feature | HiCo Magnetic Stripe Cards | LoCo Magnetic Stripe Cards |
|---|---|---|
| Coercivity | High (~2750 Oe) | Low (~300 Oe) |
| Durability | Can last thousands of swipes | Suitable for fewer uses (hundreds of swipes) |
| Security | Resistant to magnetic interference | Prone to accidental erasure or data corruption |
| Applications | High-security access, banking, ID cards | Hotel key cards, event passes, temporary membership cards |
| Encoding | Requires stronger card readers/writers | Standard readers and encoders suffice |
| Cost | Slightly higher | Lower cost |
Why Magnetic Coercivity Matters
Magnetic coercivity is crucial for several reasons:
- Data Security
HiCo magnetic stripes are harder to alter or erase, reducing the risk of fraud. LoCo cards, while convenient, can be wiped or corrupted accidentally. - Durability
HiCo cards are ideal for environments with frequent use, such as corporate access control systems or transportation cards. LoCo cards may wear out faster. - System Compatibility
High-security systems often require HiCo cards to prevent unauthorized duplication. LoCo cards are more compatible with temporary access systems. - Environmental Resistance
HiCo cards resist magnetic interference from smartphones, electronics, and other magnetic sources. LoCo cards are more vulnerable in high-tech environments.
Practical Applications of HiCo and LoCo Magnetic Stripe Cards
HiCo Magnetic Stripe Cards
HiCo magnetic stripe cards are commonly used in environments that demand high security and frequent usage:
- Corporate and Government Access Cards: HiCo cards are ideal for securing office buildings, laboratories, and government facilities.
- Banking and Financial Cards: Credit, debit, and ATM cards often use HiCo stripes to protect sensitive financial data.
- Transportation and Transit Systems: Metro, bus, and train cards benefit from HiCo durability for thousands of daily swipes.
- High-Security Membership Cards: Gyms, clubs, and facilities requiring controlled access rely on HiCo magnetic stripes.
LoCo Magnetic Stripe Cards
LoCo magnetic stripe cards are best suited for short-term or low-frequency applications:
- Hotel Key Cards: LoCo cards are cost-effective for short-term guests.
- Event or Conference Badges: Temporary access cards that don’t need high security.
- Membership Cards: LoCo cards work well for clubs or gyms with limited usage.
- Promotional or Gift Cards: Cards used for marketing or temporary purposes.
Encoding and Security Considerations
The choice between HiCo and LoCo magnetic stripes also affects card encoding and security measures:
- Card Readers and Encoders: HiCo cards require high-coercivity encoders for writing and reading, while LoCo cards work with standard magnetic stripe devices.
- Encryption: Both HiCo and LoCo cards can store encrypted data, but HiCo cards are more secure for sensitive applications.
- Integration: HiCo cards integrate well with multi-technology security PVC cards that combine magnetic stripes, RFID, and smart chips.

Maintenance Tips for Magnetic Stripe Cards
Even the most secure card can fail without proper handling. Here are some maintenance tips:
- Avoid scratching or bending the card.
- Keep the card away from strong magnets (especially LoCo cards).
- Clean the magnetic stripe with a soft cloth if it becomes dirty.
- Use high-quality encoders and readers to prevent data corruption.
Proper care ensures your PVC access cards last longer and perform reliably.

Frequently Asked Questions (FAQ)
1. What is magnetic coercivity in PVC access cards?
Magnetic coercivity measures a magnetic stripe’s resistance to being erased or demagnetized. High coercivity (HiCo) cards are more secure and durable, while low coercivity (LoCo) cards are easier to encode but less resistant to magnetic interference.
2. What is the difference between HiCo and LoCo magnetic stripe cards?
HiCo magnetic stripe cards have high coercivity (~2750 Oe) and are ideal for high-security applications like corporate access, banking, and transportation. LoCo magnetic stripe cards have low coercivity (~300 Oe) and are suitable for temporary uses like hotel key cards, event badges, and promotional membership cards.
3. Which PVC access cards are better for long-term use?
HiCo magnetic stripe PVC cards are better for long-term and high-frequency use because they resist wear, magnetic interference, and accidental data loss. LoCo cards are best for short-term or low-frequency applications.
4. Can LoCo cards be used in high-security systems?
LoCo magnetic stripe cards are generally not recommended for high-security systems because their low coercivity makes them easier to erase or duplicate. For high-security access control, HiCo magnetic stripe cards are preferred.
5. How are HiCo and LoCo magnetic stripe cards encoded?
HiCo cards require high-coercivity encoders and readers, while LoCo cards work with standard magnetic stripe encoders. Both types can store encrypted data and integrate with access control systems.
6. What are common applications of HiCo magnetic stripe cards?
HiCo magnetic stripe cards are used for corporate access control, government ID cards, banking and financial cards, transit passes, and high-security membership cards.
7. What are common applications of LoCo magnetic stripe cards?
LoCo magnetic stripe cards are commonly used for hotel room keys, event passes, temporary membership cards, and promotional or gift cards.
8. How can I maintain my magnetic stripe PVC cards?
To extend the lifespan of PVC access cards, avoid bending or scratching them, keep them away from strong magnets, clean the magnetic stripe with a soft cloth, and use high-quality encoders and readers.
9. Can HiCo and LoCo cards be combined with other security features?
Yes, both HiCo and LoCo magnetic stripe cards can be combined with RFID chips, smart chips, holograms, or UV printing for added security and functionality.
