What did credit cards previously use?
Before the glue on the back of credit cards was introduced, credit cards used to have raised lettering. The problem with raised lettering was that it made it easy to reproduce credit cards, leading to fraudulent activity. Additionally, the raised lettering made it difficult to fit the card into certain machines for swiping. As a result, credit card companies began to experiment with different methods for securing data on credit cards. One of the earlier methods was the use of metallic strips on the back of cards. However, these were bulky and not very user-friendly.
Another method used was the embossing of information onto credit cards. This method was put into practice in the 1950s, making use of manual embossing machines. Credit card machines used for processing would press a carbon paper onto the raised numbers. These would then transfer onto the receipt, creating a paper trail. While this was a secure method for credit card processing, the system was prone to errors, and the embossing was not very durable. Cards that were embossed would often lose the raised characters with continuous use and wear and tear.
Recognizing these limitations with the old methods, credit card companies started researching and developing alternatives that were more practical and user-friendly. The use of adhesive-backed cards proved to be a reliable and convenient solution, which led to the introduction of the glue on the back of credit cards.
These days, the advent of digital technology has revolutionized the way credit card information is processed. Chips embedded in the cards and contactless payment technology have reduced the need for traditional processing methods. However, the use of adhesive-backed cards remains an important security feature ensuring that credit card information cannot be easily tampered with.
