RFID Wallet Quality Control: AQL Inspection Checklist

Quality control is where wallet programmes live or die. A beautiful sample on your desk becomes a return-filled Amazon listing if production QC fails. This checklist is what TOPWALLET uses on our own production floor — and what you should ask any manufacturer to walk you through.

The Five-Gate QC Model

Every order at TOPWALLET passes five inspection gates. Each gate has a sign-off step, a documented record and retained samples. If an issue appears at your end, we can trace it back to the exact shift, batch and operator.

Eight Lab Tests, Every Batch

Beyond the five gates, every batch goes through eight laboratory tests. RFID shielding is verified on a 13.56 MHz calibration bench. Pop-up mechanisms are cycled 10,000–20,000 times on the actuator rig. Retention bands are fatigue-tested to 25,000 cycles. Metal hardware passes 48-hour salt spray. Bifold hinges survive 20,000 fold cycles. Colour consistency is measured by spectrophotometer (ΔE < 1.5). Edge paint adhesion is tested by ISO 2409 cross-hatch. Drop test: 1.2m onto concrete, plus 50kg static load.

What to Ask Your Manufacturer

Run every candidate factory through this list and require written answers. A real manufacturer answers in a day; a trading company stalls.

1. Will you share your QC checklist and the AQL level for each gate?
2. Do you retain samples from every batch, and for how long?
3. Can you show the test report for RFID shielding, mechanism cycles and dimensional checks — with the batch and shift recorded?
4. What happens to rejected units, and will you rework or replace them within an agreed window?
5. Who signs off each gate, and can I trace a defect to a specific operator and shift?
6. Will a third-party inspection be allowed, and who pays if it fails?
7. What is your claim and credit policy for defects found after shipping?

If the answer to any of these is vague, that is the QC plan you will actually get on the production floor.

Reading Your QC Report

A useful report names the batch, the shift, the operator and the sample rate — not just “passed”. Look for incoming material certs, first-article dimensional data against CAD, in-line AQL results, the 100% functional-test count, and the outgoing packaging check. A report with no sample rate and no measured values is a certificate of optimism, not a QC record.

QC Red Flags

• No retained samples, or samples you are not allowed to request.
• AQL numbers quoted without saying which gate they apply to.
• RFID shielding claimed without a frequency or test method.
• “100% inspected” used to hide a missing functional test.
• No defect-credit policy in the quotation.

Frequently Asked Questions

Q: What is AQL 0.65?
A: Acceptable Quality Level 0.65 means that 0.65% of defects are acceptable in a batch sample. This is the consumer electronics benchmark.

Q: Do you provide batch test reports?
A: Yes. Every shipment includes a QC report with RFID test results, dimensional measurements and retained sample IDs.

Q: What is your warranty policy?
A: 12-month structural warranty. Defect claims reviewed within 48 hours. Confirmed defects credited on the next order.

Q: What should a first-article report contain?
A: CAD overlay of measured dimensions, material certification, and photos of the approved sample — signed off before mass production starts.

Q: Is AQL 1.0 or AQL 0.65 right for wallets?
A: AQL 1.0 on minor cosmetic points and AQL 0.65 on critical/functional defects is the pragmatic split — which is exactly why the factory separates the in-line gate from the outgoing gate.
