- An NFC chip typically keeps its data for around 10 years, and some chip types are rated for up to 50.
- Reading a chip, the tap a customer makes, does not wear it out, so a review plate can be tapped hundreds of thousands of times.
- Only rewriting the link uses up the chip's limited write cycles, and most chips handle around 100,000 of those.
- There is no battery, so nothing runs flat; the chip draws power from the phone for the split second it is read.
- In practice the plate's material, not the chip, sets the real-world lifespan, usually several years or more.
What this guide covers
An NFC chip lasts roughly 10 years for data retention, with some chip types rated up to 50, and it can be read hundreds of thousands of times without wearing out. The number that worries people, write cycles, almost never applies to a review plate, because that limit is only consumed when you rewrite the link, not when a customer taps to read it. This guide separates the two figures that get confused, retention versus write endurance, explains why a passive chip has no battery to die, and shows why the plastic around the chip usually gives out long before the electronics do. Start with the short answer, then we will explain why it holds up so well.
How long an NFC chip lasts: the short answer
A passive NFC chip stores its data for about 10 years under normal conditions, and higher-end chips are specified for far longer. It has no power source of its own, drawing a tiny amount of energy from the phone during each tap, which is why it needs no battery and no maintenance.
For a counter device that opens your Google page, that lifespan comfortably outlasts the practical life of the product, which is exactly why a Google review plate built around a quality NFC chip keeps working day after day with no upkeep. The deeper detail behind that tap, and how it opens your page, is covered in our explainer on how a tap card works.
Why tapping never wears the chip out
Here is the key distinction most people miss: reading an NFC chip and writing to it are different operations with different limits. A customer tapping the chip to open your page is a read, and reads are essentially unlimited. They do not consume the chip's lifespan in any meaningful way.
This is why claims about a chip surviving hundreds of thousands of taps are credible. The taps are reads, and the chip's memory is only stressed when you actively overwrite its stored link, which a typical business does once at setup and rarely again.
Write cycles, and when they actually matter
The figure you will see quoted, around 100,000 write cycles, refers to how many times the chip's memory can be erased and rewritten before it becomes unreliable. It is a real limit, but it only applies to writing, which for a review plate happens once when the link is set.
Data retention is not a function of the tag but of the chip's memory. Most chips use EEPROM, for which vendors typically specify around 100,000 write cycles and a 10-year lifetime, guaranteed even at the extremes of the operating temperature range.

You could update your destination link many times a year for decades and never come close to the ceiling. Whether you can rewrite it at all depends on the product, a point our breakdown of NFC compatibility with iPhone touches on alongside which phones can read and write tags.
What really limits real-world lifespan
In practice, the chip almost never fails first. The physical body around it does. Most NFC tag failures are mechanical, not electronic: a cracked antenna from bending, UV fading, water or chemical damage, abrasion, or adhesive that gives out. The electronics keep their data for a decade while the casing wears.
- Choose a rigid, well-built plate for a counter, where it will not be bent or flexed.
- Keep it out of direct, prolonged sun and away from harsh chemicals.
- Mount it somewhere it will not be knocked, scraped or pressure-washed.
- Expect a thin paper or cheap sticker tag to survive heavy outdoor use for years.
- Flex or bend a tag repeatedly, which is what actually breaks the antenna.
- Assume a chip has failed when the real issue is a damaged or detuned body.
What this means for a review plate
For a Google review plate, the takeaway is reassuring. The chip will hold your link for roughly a decade, the constant customer taps are reads that never wear it down, and the one-time link write barely dents the write budget. The plate's rigid build is what determines how long it survives on your counter, and a solid plexiglass plate is made to last for years.
That durability is part of why a single purchase covers the hardware with no subscription: there is no battery to replace and no part that degrades with normal use. If you want the wider case for whether these tools earn their place at all, our piece on whether review cards actually work covers the adoption and results side.
How to make a tag last longer
If longevity is a priority, the levers are all physical. Pick a rugged form factor for the environment, a rigid plate indoors or a properly rated tag outdoors, avoid mounting on bare metal without the right backing, and keep it away from heat, UV and moisture. Do those, and the chip's 10-year-plus electronics will be the part you never have to think about.
The honest summary is that NFC longevity is rarely an electronic question and almost always a material one. Match the build to where it lives, and a quality tag quietly does its job for years, delivering the same instant tap on day one and day one thousand.
Frequently asked questions
How long does an NFC chip last?
The chip retains its data for around 10 years under normal conditions, and some chip types are rated up to 50. Real-world lifespan is usually set by the tag's physical material rather than the chip, so a well-built plate typically lasts several years or more, with the electronics outlasting the casing.
Does tapping an NFC tag wear it out?
No. Tapping to open a link is a read, and reads are effectively unlimited. A review plate can be tapped hundreds of thousands of times without degrading. Only writing, meaning overwriting the stored link, uses the chip's limited write cycles, and that happens once at setup, not on every customer tap.
Do NFC chips need a battery?
No. Passive NFC chips have no battery. They draw a tiny amount of power from the phone's field for the split second they are read, then go dormant. That is why they need no charging or maintenance and can sit unused for years and still work the moment a phone taps them.
How many times can an NFC tag be rewritten?
Most common NFC chips are rated for around 100,000 write cycles, and some for far more. For a review plate, the link is usually written once at setup, so this limit is never a concern. You could update the destination many times a year for decades without reaching it.
What usually makes an NFC tag stop working?
Physical damage, not the chip. The common causes are a cracked or detuned antenna from bending, UV fading, water or chemical exposure, abrasion, or failed adhesive. The chip's memory typically keeps its data for a decade, so when a tag fails early, the body is almost always the reason.
The reassuring reality of NFC is that the part doing the work, the chip, is also the part you never have to worry about: it holds its link for roughly a decade, shrugs off unlimited taps, and has no battery to die. What sets the real lifespan is the body around it, which is why a rigid, well-made plate matters more than any spec sheet. If you are choosing a review tool for a counter, the question is not whether the chip will last, it is whether the build suits where it will live. So where will yours sit, and is the format tough enough for that exact spot?
