The basics
NFC is the same tap-to-pay technology, applied to a key.
NFC — near-field communication — is what lets your phone pay by tapping a reader. An NFC key tag is a small chip attached to a key set; tap it to a reader and the system instantly knows which car it belongs to. No number to write, no number to read back.
How it works
From tag to identified car
The flow
The pitch is real: tapping is faster and less error-prone than handwriting and matching a number.
→For the key-handling part of the job, a tap genuinely beats a handwritten stub.
Where they help — and the question to ask first
NFC tags solve a real problem. But before you buy a drawer full, ask what problem you're actually solving.
Helps
Key identification
Faster, more accurate matching of keys to cars than a handwritten number.
Helps
An audit trail
Each tap can leave a record of who handled which key, when.
But
It's still hardware
Tags to buy and replace, readers to maintain — a cost that compounds at scale.
Ask first
What about the guest?
Tags help the back-of-house. They don't help the guest pay, tip, or request from their phone.
→An NFC tag improves how you handle keys. It does nothing for the guest's side of the experience.
Where Valletto changes the math
Key tags solve one step. The guest experience is the bigger prize.
NFC tags are a fine upgrade for key handling. But the larger opportunity is the guest's side — letting them request, pay, and tip from their phone — which a tag on a keyring doesn't touch.
The takeaway: NFC key tags are a real improvement for identifying keys. Just be clear that's a back-of-house win. The experience guests actually feel lives on their phone — which is where Valletto focuses, with or without a tag on the key.
