Consumers are often asked by vendors to provide credit card details manually, whether over the phone, via email, or by filling in physical forms. While this may seem like a convenient practice, it exposes both the customer and the business to significant security, privacy, and compliance risks. With the rise of digital payments and strict financial regulations, businesses must carefully consider whether such a policy is ethical, legal, and safe to implement.


Consequences for Consumers


When customers share their credit card information manually, they are essentially giving sensitive financial data without the protection of encryption or secure payment gateways. The risks include:




Example: A Sydney-based customer emailed their card details to a small vendor. The email account was later compromised, resulting in multiple unauthorised transactions. The customer had to block their card and go through a lengthy fraud investigation process.



Regulatory and Legal Implications for Businesses


Businesses are required to follow the Payment Card Industry Data Security Standard (PCI DSS). Storing or manually processing credit card data without proper safeguards often breaches these standards. Consequences for businesses include:



Should Businesses Have This Policy?


Allowing manual collection of credit card details is not recommended in modern digital environments. Secure alternatives such as payment gateways, encrypted portals, or third-party payment processors should be adopted. These methods ensure compliance with Australian Consumer Law and PCI DSS while protecting customers from fraud.


What’s Wrong with Manual Credit Card Policies?


The core issue with manual handling is the absence of security. Storing card numbers on paper or in email inboxes directly contradicts cybersecurity best practices. In an age where cybercrime is on the rise, continuing such policies is both outdated and irresponsible.


Businesses that fail to upgrade to secure digital payment systems risk legal consequences, customer dissatisfaction, and potential financial collapse in the event of a breach.


Conclusion


Giving credit card details manually to vendors  is a high-risk practice with serious consequences for both consumers and businesses. Organisations should discontinue this policy and invest in secure, compliant payment solutions. Protecting customer data is not only a legal responsibility but also a critical element in building long-term trust and credibility in the market.
