RFID in a laundry is a battery-free chip, sewn into each linen item, that a reader identifies by radio. It lets you read a full cart without unloading it, so you know what left, what came back and how many washes each piece has had. In our operation, checking a cart takes 30 seconds; counting it by hand can take up to 2 hours.
RFID stands for radio-frequency identification. It's the technology behind many toll tags and the anti-theft labels in some clothing stores, adapted to survive hot water, chemicals and pressing.
How the chip works
The tag holds a chip and an antenna inside a flexible casing. It's about the size of a clothing size label and gets sewn into the hem. It has no battery: when it enters a reader's field, the radio signal gives it the energy to answer with its unique number.
Laundry tags usually run on the UHF band, between 860 and 960 MHz depending on the country, under the EPC Gen2 standard (ISO/IEC 18000-6C). That lets one reader identify many pieces in seconds without seeing each one or aiming at it, which a barcode would require.
What it survives
Textile tags are built for industrial washing. Manufacturer datasheets commonly list around 200 cycles, sometimes with a time limit such as 2 years. The figure varies by model, so confirm it for the specific tag and for your wash process.
The chips we use withstand more than 200 industrial washes. That covers the working life of most hotel linen, since the fabric usually wears out first.
What gets recorded at each step
The chip only stores a number. Everything else lives in the system, which ties that number to the piece:
- Registration: item type, client and the date it went into service.
- Pickup: what left, how many pieces and at what time.
- Delivery: what came back, compared against what was collected.
- Washes: how many cycles each piece has had and how much life it has left.
- Missing and damaged: pieces unseen for more than 30 days and pieces written off.
What changes day to day
The first change is that nobody counts by hand. The cart goes past the reader and the system gives a total by item. In a mid-size hotel, that frees up as much as 2 hours of a housekeeper's day.
The second is that the count stops being a matter of opinion. The hotel and the laundry see the same record, with times and piece counts, so a discrepancy gets checked piece by piece instead of negotiated on the invoice.
The third takes longer to arrive. Once you know how many washes each piece has had, you can budget replacements from data and see which items wear out first.
Where it falls short
RFID isn't magic, and it's worth knowing its weak spots before you pay for it:
- Range varies. Our chips read at up to 30 m in good conditions, but the real distance depends on the reader, the antenna, moisture, how densely linen is stacked and how pieces are oriented.
- Wet pieces, tightly packed piles and nearby metal make reading harder. That's why scanning happens at set points, with linen in known conditions.
- The chip doesn't stop theft. It tells you a piece is missing and when it was last seen. Catching it on the way out takes arches at the doors.
- There's a startup cost: tagging and registering the whole inventory takes time, and readers are either bought or included in a service.
Is it worth it for you?
It depends on your volume and how much losses hurt. With few pieces and a team that counts well, a signed sheet may be enough. With thousands of pieces, several floors or an outside laundry you argue with over counts, piece-level control pays off sooner. The honest way to find out is to work out what losses and counting hours cost you today.
On Clean offers it two ways. With full service, we do the washing and the system is included, with no installation fee and no monthly charge for the system. With the system only, you keep your own laundry and we install the controls. Today we have more than 5,000 pieces tagged and tracked, and clients check everything through a read-only link, with no login and no app.
