What are the security risks of digital receipts?

Digital receipts offer significant advantages over paper, but they are not without risks. Understanding the security considerations helps you use them safely.

Email phishing

Fraudulent "receipt" emails are a common phishing vector. An email that appears to be a receipt from a known retailer may contain malicious links or attachments designed to steal login credentials or install malware. Signs to watch for: unexpected charges for purchases you did not make (designed to make you click), sender addresses that do not match the brand's domain, and urgency language ("your account will be charged unless you cancel").

Data in transit

Email is not an inherently secure channel. Receipts sent by email may pass through multiple servers before reaching you. For most transactions, this is an acceptable risk — the information is not more sensitive than what appears on a paper receipt that could be read by anyone who handles it.

Data breaches

Email receipt data stored with a retailer, receipt app, or email provider is subject to the security practices of those organisations. A breach could expose your purchase history, email address, and transaction amounts. For this reason, choosing reputable services with strong security practices matters.

Privacy

Your email receipt history constitutes a detailed record of your purchasing behaviour. Retailers and receipt aggregation apps may use this data for marketing or sell it to data brokers. Read the privacy policy of any app you use to understand how your data is handled.

Reducing risk

• Use a separate email address for commercial receipts
• Enable two-factor authentication on your email account
• Choose receipt apps that are transparent about data use
• Do not click links in unexpected receipt emails — go directly to the retailer's site instead
