How does an embosser work

[chushpan]

An embosser is a device used to create raised symbols on plastic cards such as bank cards, loyalty cards or ID cards. The raised symbols (usually the card number, cardholder name and expiration date) can be used to imprint information on checks or other documents using carbon paper. Let's look at how an embosser works and where it is used.

1. The main purpose of the embosser​

The embosser was originally created to:

• Apply personalized information to plastic cards.
• Provide the ability to quickly read data manually (for example, when printing information on checks).
• Create long-lasting, clear symbols that are difficult to erase or change.

2. How does the embosser work?​

2.1. Operating principle​

• An embosser uses a mechanical process to create raised symbols on a card:
  • The plastic card is placed into the device.
  • Metal stamps (or dies) press symbols onto the surface of the card under pressure.
  • As a result, the symbols become raised on one side of the card and recessed on the other.

2.2. Stages of work​

1. Data preparation:
   • Information (card number, cardholder name, expiration date) is entered into the device manually or via a computer.
2. Loading map:
   • A blank plastic card is placed into the device slot.
3. Application of symbols:
   • Stamps with the required symbols rise and under pressure create raised marks on the map.
4. Quality control:
   • After embossing, the characters are checked for clarity and accuracy.

3. Types of embossers​

3.1. Hand embossers​

• Compact devices that are used to create maps manually.
• Used in small organizations or for emergency situations.
• Example: portable embossers for issuing temporary cards.

3.2. Automatic embossers​

• Professional computer controlled devices.
• Capable of processing a large number of cards in a short time.
• Often used by banks and companies for mass issuance of cards.

3.3. Combined devices​

• Combine embosser functions with other technologies:
  • Application of magnetic strip.
  • Printing chips.
  • Laser engraving.

4. Where is the embosser used?​

4.1. Bank cards​

• Most bank cards have embossed symbols:
  • Card number.
  • Holder's name.
  • Validity period.

4.2. Loyalty cards​

• Loyalty programs often use embossed cards for personalization.

4.3. Identity cards​

• Some ID cards have embossed data for increased security.

4.4. Cloning cards​

• Important: Embossers are sometimes used for illegal purposes, such as creating clones of bank cards. This is illegal and punishable by criminal liability.

5. Advantages and disadvantages of embosser​

5.1. Advantages​

• Durability: Raised characters are resistant to abrasion.
• Convenience: Information is easy to read even without technology (for example, through carbon paper).
• Personalization: Ability to quickly create unique cards.

5.2. Disadvantages​

• Limitations: Modern technologies (e.g. contactless cards) make embossing less relevant.
• Speed: Manual embossers are slow compared to automatic machines.
• Counterfeiting Risk: Embossers can be used to create counterfeit cards.

6. Contemporary relevance​

With the development of digital technologies, the role of embossing is decreasing:

• Many modern cards (for example, contactless cards) do not require raised symbols.
• Most transactions are conducted online, where embossed data is not required.
• However, embossers are still used to issue classic bank cards and documents.

7. Conclusion​

An embosser is a device that has played an important role in the development of bank cards and identification systems. Although its use is gradually declining, it remains an important tool for creating personalized cards.

Key Takeaway: Embossers are reliable devices for applying raised symbols to cards, but their use is limited by current technology. It is important to remember that using embossers for illegal purposes (such as card cloning) is strictly prohibited and punishable by law.
