RFID chip buying guide for phone stickers and cards

Updated: 23 October 2026

You are looking at white discs or blank cards on amazon.co.uk, and the title says RFID chip as if that were one product. A sticker your phone can open, a card a door reader might accept, and a 125 kHz fob are three different radios. This checklist rejects the wrong frequency, the wrong memory, and a sticker meant for a metal tool, before you compare star lines. The ten kept listings sit in the [RFID chip comparison](/hub/electronic-surveillance/rfid-chip). Peter F. updated it on 21 October 2026 from those listings, NXP's NTAG notes, and Ofcom IR 2030. This is not a lab test, and a qualifying purchase can earn a commission at no extra cost to you.

What an RFID chip means here

In this set an RFID chip is a passive sticker or a blank card, not a USB reader. Kept packs run from £5.69 to £9.99: round or rectangle NFC stickers, plus one writable-UID card ten-pack. A URL wants an NFC Forum Type 2 tag. A door or printer often wants MIFARE Classic. A phone can open a page from a sticker and still ignore a Classic card with no NDEF record. Only the OFFCUP 50-pack, the InnoHHustle NTAG213 rectangles, and the FusyTuly cards print 13.56 MHz. Other stickers leave frequency as n/a. Write steps are on how to program an NFC tag.

Frequency before memory

These NTAG stickers sit at 13.56 MHz under ISO/IEC 14443 Type A. NXP places NTAG213, NTAG215, and NTAG216 there, up to about 100 mm when the antenna allows it. A 125 kHz fob cannot hear a 13.56 MHz card. Universal Contacts, a UK gate supplier, treats a phone tap as proof of NFC, not as proof a gate reader will take the token. The FusyTuly cards at about £9.99 are the only kept door-card shape, and only after you confirm 13.56 MHz and a Classic-style reader. Ofcom IR 2030 row IR2030/13/1 is a spectrum note, not an approval of a pack and not a licence for a URL sticker.

Memory, form, and surface

NXP's user memory is 144, 504, and 888 bytes. A 25 mm round sticker suits a laptop lid or a plastic bin. An 11 × 21 mm rectangle suits a narrow label, but two InnoHHustle listings print a second size, so measure one sticker first. The FusyTuly cards are 86 × 54 × 0.84 mm. Six kept stickers say not for metal or strong magnets. The 594-review NTAG215 pack does not, and UK reviews still fail on bare metal unless a non-metal pad is added. If the surface is metal, read NFC sticker on metal. A 5.0 from one review is not 4.5 from 594.

What to do with a conflicting listing

The InnoHHustle NTAG215 50-pack at about £6.99 says PVC in the bullets and paper in the material row, transparent in the title and white in the colour field. One NTAG216 20-pack prints 11 × 21 mm and 21 × 21 mm. The NTAG213 rectangles print 10 × 20 × 0.15 mm and also 1.8 × 0.8 cm. The OFFCUP 50-pack at about £5.99 is titled NTAG213 with 144 bytes, while a UK TagWriter scan reported 492 bytes and other UK reviews call it NTAG215. Scan the first sticker before you stick the rest. The £5.99 pack titled NTAG216, 3.0 from two ratings, has a UK review that says the silicon is not NXP NTAG216.

Common questions

Is an RFID chip in this shop a sticker, a card, or a reader?
In the ten listings kept here it is a passive sticker or, in one case, a pack of blank cards. It is not a desktop reader and not a loose chip. The comparison is built from amazon.co.uk packs between £5.69 and £9.99. If the product has a USB plug or a screen, it is outside this page.
Will a 125 kHz fob work with a phone?
No. Phone NFC and these NTAG stickers are 13.56 MHz. A 125 kHz fob and a 13.56 MHz card do not interoperate, which UK gate suppliers state in plain terms. A successful phone tap only shows that the sticker and the phone share a radio. It does not enrol the sticker on an older gate reader.
How much user memory do you actually need?
NXP's figures are 144, 504, and 888 bytes for NTAG213, NTAG215, and NTAG216. A short URL fits in 144 bytes. Buy 504 or 888 only when the record you will write needs that room. More memory does not improve the scan. The versus page sets out which record belongs on which chip.
Does a bigger chip scan from further away?
No. NXP quotes up to about 100 mm for the whole family, depending on the antenna and the phone. A listing that prints 0–10 cm, such as the OFFCUP pack and the NTAG213 rectangles, is in that same close range. UK reviews on the round packs still describe the handset sitting on the sticker. Distance is antenna and placement, not the byte count.
What should you check before a door or printer card?
Confirm the reader is 13.56 MHz and that it expects a Classic-style card, which is what the FusyTuly listing asks you to check. The pack is about £9.99 for ten cards, with 5.0 from two UK reviews, so it is a small test, not a surveyed system. A shared door should be issued by whoever already administers that reader. Do not use a sticker pack as a substitute card.
Why do two lines on one listing disagree?
Marketplace pages often combine a title, feature bullets, and a specification table that were not edited together. This set includes PVC against paper, two sticker sizes, and a chip name UK reviews do not all confirm. Quote both lines or skip the row. Do not invent a middle figure the page never printed.
