NTAG213 vs NTAG215 vs NTAG216: Which NFC Chip Does a Business Card or Review Card Need?

If you are comparing NTAG213 vs NTAG215 vs NTAG216, here is the short answer: for a business card, a Google review card, a social follow card or a counter stand that opens a single link, NTAG213 is enough. NTAG215 and NTAG216 only add storage (504 and 888 bytes of user memory instead of 144), and a web link takes a small fraction of even the smallest one. The bigger chips earn their place only when you want to store more than a link directly on the chip, or when a specific app demands them.

That is the whole decision for most UAE businesses. The rest of this guide explains where the numbers come from, what the three chips share, the few cases where the bigger ones make sense, and what to ask a supplier so you do not pay extra for memory you will never fill.

What NTAG213, NTAG215 and NTAG216 actually are

All three are NFC chips made by NXP Semiconductors and sold as one product family. NXP's own datasheet, NTAG213/215/216: NFC Forum Type 2 Tag compliant IC with 144/504/888 bytes user memory, describes them as one family that differs mainly in how much memory each member has. They follow the NFC Forum Type 2 Tag standard, which is why a modern iPhone or Android phone can read any of them without an app for the basic job of opening a link.

The family name is easy to remember once you know the pattern: the number is a rough size class, not a quality grade. A higher number does not mean a stronger signal, a longer range or a more secure card. It means more room to store data.

The numbers side by side

These figures come from the NXP datasheet. The "total memory" figure includes manufacturer and configuration areas that you cannot use. The "user memory" figure is the part you can actually write to.

Chip	Total memory	User memory (read/write)	Rough capacity
NTAG213	180 bytes (45 pages)	144 bytes	about 130 characters
NTAG215	540 bytes (135 pages)	504 bytes	about 480 characters
NTAG216	924 bytes (231 pages)	888 bytes	about 850 characters

The "rough capacity" column is a common rule of thumb quoted by NFC suppliers for plain text; real capacity is a little lower because the data is wrapped in a small amount of formatting. We cover that overhead below.

What all three have in common

This is the part most comparison pages bury, and it is the most useful for a buyer. According to the same NXP datasheet, the three chips share these specifications:

• Operating frequency: 13.56 MHz, the standard NFC frequency, so every NFC phone can talk to them.
• Input capacitance: 50 pF on all three variants. This is one of the numbers that affects how an antenna is tuned, and it is identical, so you should not expect one chip to read from further away than another when the antenna is the same.
• Data retention: 10 years.
• Write endurance: 100,000 write cycles. For a card that is programmed once and then read thousands of times, this is irrelevant in practice. Reading does not wear the chip out.
• Features: an originality signature based on elliptic-curve cryptography, an NFC counter that can count reads, and optional password protection.

In other words, the extra money for NTAG215 or NTAG216 buys memory only. It does not buy a faster read, a longer range or better durability. If anyone tells you a bigger chip will make your card scan more reliably, ask them to show you where that comes from, because it is not in the datasheet.

How much memory does a link really need?

Most business cards, review cards and follow cards store one thing: a web address. A web address is stored as an NDEF record, the standard data format phones understand. A short URL record carries only a handful of bytes of overhead (a few bytes of record header plus a few for the tag's own wrapper, so roughly eight in total), and the address itself is the rest. NFC phones also shorten common prefixes such as https://www. into a single byte, so the chip stores less than you might expect.

Take an example of a Google review link. Google's Business Profile tool gives you a short link of about 30 characters in the form g.page/r/XXXXXXX/review, according to guides on how to find your Google review link. That fits easily inside the 144 bytes of an NTAG213, with well over 100 bytes to spare. Even a long tracking link with several parameters of 80 to 100 characters still fits.

Here is when 144 bytes starts to feel tight:

• Storing a full contact (vCard) directly on the chip. A vCard with a name, company, two phone numbers, an email, a website and an address can easily exceed 144 bytes and may be close to or beyond 300. That is where an NTAG215 (504 bytes) becomes useful.
• Several records on one chip. For example a link plus a phone number plus a Wi-Fi record. NTAG216 (888 bytes) handles this.
• Long URLs with lots of tracking parameters. Rarely needed, and usually a sign the link should be shortened instead.

But there is a better answer for most businesses than buying a bigger chip: store a short link on the chip, and let that link open a page that holds all the details. The page can hold a full contact card, a menu, ten links and a photo, and you can edit it later without touching the card. That is how an editable digital profile works, and it is the reason most professional NFC cards use the smallest chip. We explain the trade-off between printed and editable cards in our guide to paper business cards vs an editable digital card.

When NTAG215 makes sense

NTAG215 is the middle chip, and its reputation comes mostly from outside business use. GoToTags, a US NFC supplier, describes it as popular in gaming and recommends it "only when additional memory is required." Nintendo's Amiibo figures are the best-known example of NTAG215 in the wild, and that is why many people have heard of it before any other NTAG number.

For a UAE business, choose NTAG215 if:

• You want a contact card saved to the phone straight from the chip, even if the person is offline and your profile page is not reachable.
• You have an app, a loyalty system or a door/access project that specifically lists NTAG215 as a requirement.
• You are buying blank cards for your own programming and want headroom. Blank NTAG215 cards are sold widely: a search listing on Carrefour UAE showed a pack of 100 black NTAG215-class (504 bytes) blank cards at around AED 2.22 each including VAT. Prices like this move, so check the current listing rather than treating it as fixed.

Some UAE sellers lead with the bigger chip in their listings. For example, NEOTECH in Dubai lists a matte black social media digital business card as "NTAG 215 NTAG 216", with the price shown as available on request. That is a fair product, but notice the chip is being presented as a feature. For a link-only card it is not one.

When NTAG216 makes sense

NTAG216 has 888 bytes of user memory, the most in this family. It is a niche choice for a business card. It suits cases such as storing a Wi-Fi record and a vCard and a link together, or a small data payload for a custom workflow. If you cannot name the specific thing that needs more than 504 bytes, you do not need an NTAG216. GoToTags gives the same guidance for both bigger chips: use them only when the extra memory is required.

What about newer chips like NTAG 424 DNA?

You will see other names in supplier lists. GoToTags, for example, also lists ICODE SLIX (for extended range) and NTAG 424 DNA (for cryptographic authentication). NTAG 424 DNA adds security features designed to prove a tap came from a genuine tag and to stop copying. That matters for ticketing, anti-counterfeit labels and access control. It is overkill for a card that opens a public Google review page, where the "secret" is a link anyone can find online anyway.

Read-only locking: the feature that matters more than the chip number

The more important question for a business is not 213, 215 or 216. It is whether the chip is locked. All three chips can be set to read-only so that nobody can overwrite the link. This matters because an unlocked card on a counter can, in theory, be rewritten by anyone with a free phone app. Someone could quietly point your review card at another page.

When you buy, ask directly: is the chip write-protected after programming? On Smaacaad's product pages, the All-in-One NFC Business Card is described as carrying a write-protected NFC chip. Whichever supplier you use, get the answer in writing. And keep a printed QR code on the card as well, because a QR code is the fallback for any phone that does not read the tap. Our guide on whether every iPhone reads NFC cards explains which models need extra steps.

Does chip choice affect how well a phone reads it?

Not in a way you can notice day to day. Because all three chips have the same 50 pF input capacitance and the same frequency, the antenna design and the card's surroundings dominate read performance. Those include the size and quality of the antenna coil, whether the card sits near metal, and the phone case. If you are troubleshooting a card that scans badly, switching chip numbers is almost never the fix; start with placement and cases instead.

A simple decision guide

1. The card opens one link (Google review, Instagram, WhatsApp, menu, digital profile): NTAG213.
2. The card should save a full contact on tap, even offline: NTAG215.
3. The card carries several records or a Wi-Fi plus contact payload: NTAG216.
4. The card is for access control, ticketing or anti-counterfeit: ask about NTAG 424 DNA or another secure chip, and expect a different price band.

What to ask a supplier before you order

• Which chip is inside, and can they name the exact model rather than "NFC chip"?
• Is the chip locked after programming?
• Can the destination link be changed later, and who can change it?
• Is a QR code printed on the card, and does it point to the same destination?
• Is the price per card the same whatever the quantity, and is it shipped programmed and ready?

The honest limit of this article: Smaacaad's product pages list material (PVC) and size (85 mm by 55 mm) but do not name the chip model, so ask for it when you order. We would rather tell you that than guess.

Which Smaacaad product fits

For a counter or reception desk where customers should leave a Google review, the Google Review NFC Card with QR is AED 29 per piece and the Google Review NFC Stand with QR is AED 59 per piece, both taken from the live product pages at the time of writing. For a person-to-person card with a full digital profile, the NFC Business Cards are AED 79 per piece with QR and logo included. Check the product page for the current price before ordering. All of these are link-based products, which is exactly the use case NTAG213 is designed for.

Frequently asked questions

Is NTAG215 better than NTAG213?

Only if you need the extra memory. NXP's datasheet lists the same operating frequency, input capacitance, retention and write endurance for both. NTAG215 has 504 bytes of user memory against 144 bytes, and that is the main difference.

Which NFC chip is best for a Google review card?

NTAG213. A Google review short link is around 30 characters, so it fits comfortably in 144 bytes. Pair it with a printed QR code so customers whose phones do not tap can still reach the review page.

Do NTAG213, NTAG215 and NTAG216 work with iPhone and Android?

Yes, all three are NFC Forum Type 2 tags and are read by NFC-capable phones. iPhone XR, XS and newer read tags automatically according to Apple's support guide, while iPhone 7, 8 and X need the NFC Tag Reader switched on in Control Center.

Can I change the link on an NFC card later?

If the chip is not locked, yes, up to the chip's write endurance of 100,000 cycles. If it is locked for safety, you cannot rewrite it, so the better approach is a short link that you can redirect or an editable profile page behind it.

Does a bigger chip give a longer read range?

No. The three share the same 50 pF input capacitance in the NXP datasheet, and range depends mainly on the antenna, the phone and the surroundings, not on the chip's memory size.

Our recommendation

Buy for the job, not the number. If your card opens a link, an NTAG213 card with a printed QR code and a locked chip is the sensible, lower-cost choice, and you will not feel any difference from a bigger chip. Choose NTAG215 or NTAG216 only when you can name the data that needs the space. To order a review, follow or business card programmed and ready to use, message Smaacaad on WhatsApp from any product page, or start with the Google Review NFC Card with QR.
