How to Accept QR Code Payments at Flea Markets and Garage Sales

Individuals Can Accept QR Code Payments

Introducing QR code payments at flea markets and garage sales lets you sell to buyers without cash. With Japan's cashless payment ratio exceeding 40%, many customers skip purchases when only cash is accepted. Using person-to-person transfer features on PayPay, Rakuten Pay, or Merpay requires no special equipment or merchant agreements.

The simplest method is displaying your QR code via PayPay's "Send/Receive" feature for buyers to scan. Person-to-person transfers are also fee-free. Note that this is a "person-to-person transfer," not a formal "payment transaction." Keep transfer records for sales tracking and tax filing purposes.

Preparing and Displaying QR Codes

Prepare in advance for smooth transactions on the day:

• Save your PayPay "My Code" as a screenshot and print at A4 size. Laminating protects against outdoor dirt and rain
• Add signage like "PayPay accepted" or "Cashless OK" in large, readable text
• Fully charge your smartphone (bring a portable battery too)
• Prepare cash for change as backup

If accepting multiple payment methods, displaying each QR code side by side is helpful. Supporting just PayPay and Rakuten Pay covers the majority of cashless users.

Tips to Prevent Issues

Tips to prevent QR code payment troubles:

• Verify transfers: Always confirm receipt in your own app before handing over items. Viewing the buyer's screen alone risks forgery. Cases of edited screenshots faking completed transfers have been reported
• Connectivity: Outdoor events may have unstable signal. Check venue reception in advance and bring a pocket Wi-Fi if needed
• Amount confirmation: State the amount verbally and verify on the buyer's screen before they send. Digit errors are surprisingly common

Supporting both cash and cashless is the best strategy to avoid missed sales.

Using QR Codes on Price Tags

Attaching QR codes to price tags that link to product details is another useful approach. For used electronics, linking to pages with model numbers, purchase dates, and working condition helps buyers make confident decisions. For brand items, showing purchase receipts or warranty photos builds trust.

Creating a product list in Google Sheets and converting each row's link to a QR code is straightforward. Price reductions only require updating the spreadsheet without recreating QR codes. For larger flea markets (50+ items), this also streamlines inventory management.

Sales Tracking and Tax Considerations

Flea market and garage sale revenue may require tax filing depending on annual totals. Selling personal used items is generally tax-exempt, but reselling purchased goods or selling precious metals and jewelry exceeding 300,000 yen per item is taxable.

A QR code payment advantage is automatic transfer history recording in the app. While cash transactions require handwritten records, QR payments automatically log dates, amounts, and counterparty information. Saving transfer history screenshots provides useful documentation if tax filing becomes necessary.

If annual sales are expected to exceed 200,000 yen, consult a tax office or accountant early. Ignorance is no excuse in tax matters.
