Arkansas serves roughly 107,000 registered medical cannabis patients through just 38 dispensaries, on about $296 million in 2025 sales. Bank-to-bank ACH settles the full basket next day on federally regulated banking rails, with no card network in the transaction and therefore no merchant category code to mismatch.
Nearly 2,800 patients per store means Arkansas counters run consistently busy, not occasionally.
The short version
- Arkansas serves about 107,000 patients through only 38 licensed dispensaries.
- That is roughly 2,800 patients per store, among the highest ratios in the country.
- High throughput makes the speed of the payment step an operational issue.
- Bank-to-bank ACH runs on federally regulated banking rails with next-day settlement.
The Arkansas market, in numbers
Arkansas recorded roughly $296 million in medical cannabis sales in 2025, up about 5%, across just 38 licensed dispensaries regulated by the Arkansas Medical Marijuana Commission.
The patient base is the striking number: roughly 107,000 registered patients in a state of three million. That works out to nearly 2,800 patients per dispensary, among the highest ratios in the country.
Average retail price sits near $12.80 per gram, and Arkansas draws meaningful cross-border interest from neighboring states with narrower programs.
Why card processing closes in Arkansas too
The mechanism is national, not local. Card networks require every merchant to be classified with a four-digit merchant category code when an acquiring bank boards the account, and there is no code for state-licensed cannabis. An Arkansas-licensed dispensary accepting cards is boarded under a category that does not describe it, and network monitoring is built to find exactly that mismatch.
Arkansas’s own rules do not change this. State licensing determines whether you can operate; card network operating rules are written against federal law, which has not moved. The sequence is the same everywhere: the account boards, it works for a while, monitoring flags the mismatch, and the account terminates with settled funds held, commonly for around 90 days.
Cashless ATM and PIN debit programs are common among Arkansas dispensaries and carry the same underlying structure regardless of how the terminal is labeled at the counter.
Bank-to-bank ACH as the alternative
ACH moves money directly between the customer’s bank account and the merchant’s, on federally regulated banking rails. There is no card network in the transaction, so no merchant category code applies and there is no network monitoring comparing behavior against a coded category.
At the counter the customer scans a QR code with their phone camera, connects their bank once in about thirty seconds, and confirms. No app download. Every purchase after that is a single confirmation, typically under twenty seconds. Greencard Payments platform data puts the repeat rate at roughly 87%. Funds settle next day into your own account, and cash acceptance is unaffected — this is an addition to the payment mix, not a replacement.
Throughput and the repeat patient
Medical patients are repeat customers on a schedule. They come back monthly or more often, which is the profile where a one-time thirty-second bank connection amortizes across dozens of visits rather than being a one-off cost.
At Arkansas volumes, the difference between a twenty-second confirmation and a walk to an ATM is measured in queue length across a whole afternoon. That is a staffing and throughput argument before it is a payments one.
Patient-facing outreach also matters more in a medical market. Customer details captured at the point of sale sit in your own account, and one-off emails or group campaigns run from the same dashboard — useful for restock notices and product availability rather than marketing noise.
Delivery, online and wholesale
Arkansas does not permit general dispensary delivery, so the counter and online pickup ordering carry the load. E-commerce prepay collects the full basket at online checkout, which in a 38-store state also shortens what can be a long queue.
On the supply side, wholesale between licensees still settles largely in cash and checks. B2B invoicing on the same platform settles against a specific invoice, next day, with recurring billing for standing orders, and every transaction posts to QuickBooks automatically.
Availability in Arkansas
Seay Payments is an Independent Sales Organization. We do not process payments, handle onboarding, or provide ongoing merchant support; we connect licensed operators to the platform and to the team that runs it. Bank-to-bank ACH acceptance through Greencard Payments is offered to licensed cannabis businesses, and the demo confirms availability and fit for your license type, your volume and your bank before anything is signed.
