Yes, there are free ID scanner apps, and Carded makes one. But "free" covers two different tools, and only one is built for a door.
Some free scanner apps just photograph and file your own ID or documents in a wallet. This is about the other kind: software that checks a customer's age at a bar, dispensary, or event, reads the barcode, and logs the check.
For that job, free always has a business model behind it, and at a busy door that model is the thing worth checking before you rely on it.
A scan is fast and consistent either way. The real question a free tier answers is what happens to the data it reads, and whether you're left with a record when it matters.
Here's how free ID scanner apps for the door actually make money, what a door needs a paid plan for, and where Carded's free tier fits.
How a free ID scanner app makes money
An app that reads IDs all night costs something to build and run. If you're not paying for it, the cost lands somewhere else. Usually one of three places.
Per-scan or per-venue fees. The download is free, the scanning isn't. You get a handful of reads, then a limit, then a bill that scales with your busiest nights.
Your patrons' data. Some free scanners keep everything they read and the data becomes the product. Before you trust one, ask what a scanner keeps, for how long, and whether it's shared or sold.
A stripped read with no record. The free version does the age math but keeps no usable log. You get the beep and none of the proof, which is the part that actually protects you.
The one question that matters: what does it keep?
A scan protects you two ways. It does the age check, and it leaves a record that the check happened.
In many states that record is what gives you an affirmative defense if a patron later turns out to be underage. California, for example, gives a licensee a defense under Business and Professions Code section 25660 when staff demanded, were shown, and relied on bona fide evidence of age. Rules vary by state, so treat that as background, not legal advice. The record is what carries it.
A free tier that keeps no record misses the point. So does one that keeps too much of the wrong thing.
The honest version keeps only what proves a check happened, a one-way code, an age result, and the outcome, with no name, date of birth, or ID number stored.
| Before you rely on a free scanner, ask | Why it matters |
|---|---|
| Is there a per-scan or per-venue fee above a limit? | "Free" can turn into a bill on your busiest night. |
| What does it keep, and for how long? | Stored names and birth dates are a liability you now own. |
| Is any of it shared or sold? | If the data is the product, your patrons pay instead of you. |
| Does it leave a record you can export? | No record, no proof you carded when a regulator asks. |
| Does it run offline? | A basement or a field with no signal shouldn't stop the door. |
What a door actually needs a paid plan for
A free tier is built for a slow counter or a trial run. A weekend door tends to want more, and it's usually these four things.
None of that is exotic. It's the difference between an app you test on a Tuesday and one you run on a Saturday. And if you're weighing hardware instead, that's a separate call: see app vs. handheld machine.
Carded's free tier, and where Pro starts
Carded is free to start. You scan by hand, up to 10 IDs per venue each month, and each one is kept in the same clean record with no personal details stored.
That covers a quiet counter or a trial before you commit. A busy door outgrows 10 scans quickly, which is where Pro comes in.
Pro is $14.99 a month, or $79.99 a year, which works out to about $6.67 a month. It unlocks the full door:
- Continuous auto-scan. Point and read, no tap, so the line keeps moving.
- Unlimited scans and staff accounts. No monthly cap, and every scan is tied to who ran it.
- Owner console and guest records. The Tonight view and a running record of the night, with the passback flag that catches the same ID twice.
No per-scan fees on either plan, and the record stays a clean record whether you're on free or Pro. What Carded keeps is the proof, not the person.
Here's the split at a glance:
| Free | Pro | |
|---|---|---|
| Price | $0 | $14.99/mo or $79.99/yr |
| Scans | Up to 10 per venue a month | Unlimited |
| Scanning | By hand | Continuous auto-scan |
| Staff accounts and owner console | Not included | Included |
| Guest records and the passback flag | Not included | Included |
| Clean record, no personal details | Included | Included |
| Per-scan fees | None | None |
So, is a free ID scanner app enough?
For a slow counter, a genuine free tier can be. For a weekend door, the honest answer is that free gets you scanning, and a paid plan gets you the record, the accountability, and the speed a real line needs. If you're still choosing a scanner, our guide to the best ID scanner apps for bars lays out the full criteria.
Either way, the test is the same: know what the app keeps before you point it at your patrons. A scanner that reads a barcode is doing an age check, not authenticating the card, so what you're really buying is the proof you carded.
Carded is free to start and reads the barcode, checks age, flags expired, and keeps a clean record, the proof and not the person, offline, on the phone already in your staff's pocket. Download Carded to try it on your next shift.
