Adult-use vs. medical age rules
In adult-use markets, customers must generally be 21 or older; medical programs often allow qualifying patients 18+ (and minors through a registered caregiver). Either way, the dispensary must verify a valid government-issued photo ID — and, for medical, the patient's registration credentials per state rules.
Because dispensaries operate under strict, license-conditioned regulation, age verification isn't a courtesy — it's a condition of staying open.
Check everyone, at the door
Most programs expect ID verification before entry to the sales floor, not just at the register. Scanning the ID confirms the customer is of legal age and that the ID is authentic and unexpired before they ever browse product.
Reading the barcode also removes the guesswork of borderline ages and hard-to-read out-of-state licenses.
How scanning protects the license
An ID scanner runs 60+ authenticity checks in under a second and logs a timestamped record of each verification — documentation that you performed a good-faith age check. Kred works fully offline with encrypted on-device storage, and can flag individuals across locations if you run Kred Cloud.
Follow your state's specific rules on what customer data may be recorded or retained.
Frequently Asked Questions
How old do you have to be to enter a dispensary?
In adult-use markets, generally 21+. Medical dispensaries often admit qualifying patients 18+ (or minors via a registered caregiver). The dispensary must verify a valid government photo ID, and medical programs also verify patient registration.
Do dispensaries scan your ID?
Many do, to confirm authenticity and legal age. What data may be stored varies by state — some restrict retention — so configure your process to your jurisdiction's rules.
Why check ID at the door instead of the register?
Most programs restrict the sales floor to age-verified customers, so verifying at entry keeps underage individuals out of the retail area entirely and reduces compliance risk.
