HF / NFC Application engineering
RFID Labels for Pharmaceuticals
Lot, expiry and identity readable in bulk, from the wholesale tote to the hospital kit tray, without opening a box.
Design for the real reading environment
Serialization rules such as the US DSCSA and the EU Falsified Medicines Directive give each saleable pack a unique identity, usually a 2D barcode that must be seen to be read. RFID adds what barcodes cannot: bulk verification without line of sight. A tote of mixed product can be read in one pass, a crash-cart kit checked in seconds, and short-dated lots found without inspecting shelf by shelf.
Antenza lists labels in both frequency families: HF ISO/IEC 15693 tags on NXP ICODE SLIX and SLIX2, which behave predictably at close range around liquids and in smart cabinets, and small UHF inlays (Alien Higgs-3 square, Impinj Monza 4 round) for case and tote speed.

Pharmacy and supply problems RFID targets
- 01
Expiry checks by hand
Staff check dates shelf by shelf; short-dated stock is found too late to redeploy.
- 02
Kit and tray verification
Crash carts and surgical kits are checked item by item against a paper list: slow, and errors still slip through.
- 03
Liquids and foils
Vials, ampoules and blister foil are among the hardest RF environments in packaged goods.
- 04
Serialization without bulk reads
The regulatory identity exists, but verifying a sealed tote still means opening it, unless the identity is also radio-readable.
How Antenza supports pharma labelling
Both frequencies, advised per product
UHF for distribution-speed bulk reads; HF ISO 15693 where near-field behaviour around liquids and foils is the safer choice. We advise per product and packaging level.
Small-format labels
Label size and adhesive chosen for vials, ampoules and unit cartons, including small-radius curved surfaces, and confirmed on your packaging in the sample round.
Serialized encoding
Unique identities encoded and verified before shipment, aligned to your serialization scheme.
Controlled production
Labels are converted at our ISO 9001-certified production partner, with 100% inline electrical testing of the inlays.
Typical pharma label specification
Liquid content and foil lidding change the right tag choice. Send real product samples so we can validate before you commit to a specification.

Frequently asked questions
UHF or HF for medication tagging?
Rule of thumb: UHF when you need distance and bulk speed (totes, cases, dock reads); HF ISO 15693 when items are small, liquid-filled and read in trays or smart cabinets at close range. Many programs use both at different packaging levels.
Does RFID interfere with medication or medical devices?
Passive tags have no battery and only respond when a reader powers them, and readers operate within regulated power limits. Institutional policies vary, so we provide tag documentation your compliance team can assess.
Can the labels handle refrigerated and frozen storage?
Cold storage is fine for the inlay; adhesive and face stock are chosen for the temperature profile. State the storage conditions in your inquiry.
Does RFID replace the DSCSA or FMD barcode?
No. RFID complements it: the regulatory 2D code stays, and the RFID tag adds bulk, no-line-of-sight reads carrying the same or a linked serialized identity.
