## Summary
- A women's apparel brand needed to comply with Walmart's RFID mandate across 4 product categories in 14 weeks.

## Buyer Guidance
- Best for: Case Study: 99.2% Read Rate for Walmart RFID supports RFID and NFC evaluation, comparison, and sourcing decisions.
- Compare first: Compare Case Study: 99.2% Read Rate for Walmart RFID against reader compatibility, chip family, material, and deployment environment.
- What to confirm: Confirm target application, compatibility requirements, customization needs, quantity, and sample expectations before quoting Case Study: 99.2% Read Rate for Walmart RFID.

## FAQ
- Q: Why hangtag instead of sewn-in label?
  A: Walmart allows either for these categories. Hangtag was cheaper to retrofit existing garment patterns and easier to remove at point of sale, which the brand preferred for resale-channel control.
- Q: How were duplicate EPC risks avoided across 3 factories?
  A: Brand IT pre-allocated EPC ranges per factory per week and pushed them to encoder stations every Monday. Encoders refused jobs outside their assigned range — eliminated cross-factory collision risk.
- Q: What did the Walmart audit actually measure?
  A: Three sampled cases of ~1,200 units each scanned at the RDC with Walmart's standard handheld; pass = ≥95% reads. The brand's score across the 3 cases was 99.4 / 98.9 / 99.3 = 99.2% blended.
- Q: Can this approach work for a smaller brand starting with one Walmart category?
  A: Yes. Single-category, single-factory rollouts with one encoder station typically run 8–10 weeks total and ~$18K initial capex.
- Q: Why aim for 98%+ at supplier dock when Walmart's threshold is 95%?
  A: Carton handling between supplier dock and Walmart receiving typically degrades read rate by 1-3 percentage points (truck vibration, carton restacking, wand-scan placement at Walmart RDC). A program designed for 95% at supplier dock can ship a 92-94% read at receiving — and 92% is below threshold. Designing for 98%+ at dock leaves the buffer Walmart's audit math actually requires. This is why the brand cleared 99.2% on the formal audit.
- Q: Are we required to print the EPC symbol on the hangtag or packaging?
  A: Yes for Walmart 2025+ shipments. Walmart's program guidance requires the EPC symbol prominently displayed where the RFID tag is present so associates and customers can identify RFID-bearing items. For hangtag programs, place the symbol on the printed face of the hangtag (typically lower-right corner, 5-8 mm). For sewn-in label programs, the symbol appears on the care-label print or on a co-located packaging element. Suppliers reformatting hangtags should ask their RFID inlay vendor for the official EPC symbol artwork file (it is a registered logo) — using a freehand approximation has been flagged in past audits as non-compliant. Cybra's mandate guide is the most current public reference for the symbol requirement.
- Q: What would have happened if the first audit failed?
  A: Walmart allows 2 audit attempts before chargebacks compound. A first-fail flips the supplier into remediation: a 30-day plan submission, weekly read-rate evidence, sometimes a Walmart-supplied auditor at supplier dock. The financial sting is the chargeback exposure during remediation ($2-5 per unit per failed shipment, plus per-shipment reroute fees of $50-200). For the case-study brand at ~1.6M annual units this would have run into hundreds of thousands of dollars across one quarter.
