Prepaid Card Packaging With Barcode-Blocking Tamper Evidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prepaid cards are vulnerable to counterfeiting and tampering, with fraudsters duplicating or altering barcodes to redirect funds to their accounts, rendering the genuine cards useless.
Innovation Solution
A prepaid card assembly with packaging that includes a barcode partially visible through a cutout, a hologram for authentication, and an adhesive label that remains attached to the packaging upon removal, ensuring the barcode becomes unscannable and visible as tampered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the barcode is made visible through a cutout in the packaging, then the barcode can be scanned without removing the card, but the barcode becomes vulnerable to counterfeiting and tampering
Solution Approach 1:
The adhesive label is pre-positioned to cover the barcode before the card is removed from packaging. The label is designed with differential adhesive strength so that it remains on the packaging when the card is removed, thereby preventing barcode scanning and indicating tampering before the fraudulent act can be completed.
Solution Approach 2:
The adhesive label acts as an intermediary element between the packaging and the barcode. It provides a conditional barrier that allows legitimate scanning when attached to the card, but prevents scanning and indicates tampering when removed with the packaging, thus mediating between convenience and security.
2Reliability
If an adhesive label is used to couple the prepaid card to the packaging, then tampering can be detected, but the label must be designed with complex differential adhesive properties
Solution Approach 1:
The adhesive label has non-uniform adhesive properties distributed across its surface. The first region has adhesive strength configured to remain attached to the packaging, while the second region has adhesive strength configured to remain attached to the prepaid card, creating local quality variations that enable tampering detection without requiring complex overall design.
3Object-affected harmful factors
If the barcode is made more complex with gradients and colors to prevent fraud, then counterfeiting becomes more difficult, but the barcode becomes harder to scan and read
Solution Approach 1:
The security function of preventing counterfeiting is extracted from the barcode itself and transferred to the adhesive label system. The barcode can remain relatively simple and scannable, while the adhesive label with its differential adhesive properties and tamper-evident design provides the counterfeiting protection, separating the scanning function from the security function.

AI summary
A prepaid card assembly that includes packaging and a prepaid card. The prepaid card is at least partially enclosed within the packaging. The prepaid card includes a barcode. The prepaid card is coupled to the packaging such that, upon removal of the prepaid card from the packaging, a portion of the barcode of the prepaid card remains coupled to the packaging to render the barcode of the prepaid card unscannable.
