## Description
FDA UDI (Unique Device Identifier) requires every medical device to carry a unique identifier with version data. RFID is increasingly the data carrier...

## Summary
- FDA UDI (Unique Device Identifier) requires every medical device to carry a unique identifier with version data.

## Buyer Guidance
- Best for: Medical Device UDI + RFID — A Combined Guide supports RFID and NFC evaluation, comparison, and sourcing decisions.
- Compare first: Compare Medical Device UDI + RFID — A Combined Guide 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 Medical Device UDI + RFID — A Combined Guide.

## FAQ
- Q: Is RFID required for FDA UDI compliance?
  A: No — FDA accepts barcode, RFID, NFC, and other AIDC formats. RFID is one option chosen for read speed and lifecycle persistence. Most medical-device manufacturers ship 2D DataMatrix as the primary UDI carrier; RFID is added for high-value reusable devices.
- Q: Does RFID-only labeling satisfy UDI?
  A: No. UDI requires both human-readable form (printed text) AND AIDC. RFID is one AIDC option but printed UDI must accompany. Common pattern: printed UDI label PLUS RFID tag carrying same UDI for fast machine read.
- Q: Who pays for UDI implementation?
  A: Medical device manufacturer pays UDI marking and GUDID submission. Hospital and distributor pay for reader infrastructure and integration. RFID typically adds $0.50-5 per device depending on chip and form factor.
- Q: How does UDI relate to MDR (EU Medical Device Regulation)?
  A: EU MDR has its own UDI-EU system parallel to FDA UDI. Mostly compatible (both use GS1 GTIN-14 typically) but separate database submissions. Multinational manufacturers maintain UDI records in both FDA GUDID and EU EUDAMED, with the additional EU-only Basic UDI-DI grouping for product families.
- Q: How does UDI apply to Software as a Medical Device (SaMD)?
  A: Per 21 CFR 801.50, SaMD must comply with UDI. The full UDI must appear in plain-text on startup or in a Help/About menu; the AIDC carrier (barcode/RFID) is not required to display upon startup. For non-packaged SaMD (electronic download or cloud-based), the version number serves as the Lot/Batch in the Production Identifier. Major SaMD changes (algorithms, database structures, architecture, new UI) require a new Device Identifier and a new GUDID record.
- Q: What about reprocessed single-use devices and convenience kits?
  A: FDA's 'labeler' definition explicitly includes single-use device reprocessors, convenience kit assemblers, repackagers and relabelers — each becomes the labeler responsible for UDI compliance for the version they distribute. Convenience kits and combination products carry specific exemptions per 21 CFR 801.30, but the regulated device inside the kit retains its own UDI obligation. Programs that mark only the kit and skip the component UDI are a frequent FDA-483 observation.
