CSC System is the platform behind cannabis social clubs. CSC-OS runs the club — members, stock, sales, staff and the door. CSC-PASS carries the member — one verified credential, accepted at every participating club.
A Tekzian Systems product · Built for Spanish cannabis social clubs
Most clubs run on a patchwork: a spreadsheet for members, a notebook for stock, a card machine that doesn't talk to either, and a paper list on the door. Every new member fills in the same forms they already filled in down the road.
Nobody can verify anything across clubs. A membership means nothing outside the four walls that issued it, and a club has no way to know whether the card in front of them is current, lapsed or revoked.
The same member registers from scratch at every club they visit.
A printed card proves nothing and cannot be revoked once issued.
Stock, sales and members live in separate tools that never reconcile.
Clubs have no reliable way to tell their own members anything.
They are two sides of the same platform. Either works on its own; together they close the loop between a club's records and a member's credential.
For clubs · Windows
The complete club management system, running on the club's own machine. Your business records never leave it.
For members · iOS & Android
One verified membership credential, the club directory, and everything the clubs you follow are doing.
They register with CSC-PASS, confirm their email and complete the annual membership. No club-by-club paperwork.
Once the membership is verified, a signed credential is issued to the member's app, with a QR code that encodes a verifiable token rather than personal data.
The directory shows approved clubs by city, region or distance, with the club's own profile, opening hours and contact details.
CSC-OS checks the credential against CSC System in seconds. Lapsed, suspended or revoked memberships stop working immediately.
Announcements and events published from CSC-OS or the club portal land in the member's app — only for the clubs they follow.
Only what must be checkable from anywhere: member identity, membership status, credential state, club listings, events and announcements.
Everything else. Sales, stock movements, cash reconciliation, invoices, accounting, supplier records and internal notes stay on the club's own machine and are never uploaded.
The server explicitly rejects any request that tries to push club trading records to it.
Session tokens and keys are stored hashed, never in plain text.
Every privileged action is recorded with actor, target and outcome.
CSC-OS keeps running through an outage, with a signed licence grace period.
The complete system, updates included — and your directory listing at no extra charge for as long as you run CSC-OS.
Clubs that don't run CSC-OS can still be listed. Listings are arranged with us directly rather than bought online.
One annual membership covering your credential across every participating club.
No. Clubs running CSC-OS are listed automatically at no extra charge. Clubs that don't can still be listed — get in touch and we'll arrange it.
No. CSC System holds membership and credential records only. Sales, stock, accounting and supplier data stay on your own machine — the server actively refuses requests that try to send them.
CSC-OS keeps running. It holds a signed licence cache with a grace period, so the club carries on working and re-synchronises when the connection returns. Credential verification is the one thing that needs to be live.
Yes, and it takes effect immediately. Because verification happens against CSC System at the moment the card is presented, a lapsed, suspended or revoked membership stops working straight away.
No. The QR encodes a signed verification token, not your name, date of birth or membership details. It only means something to a club checking it against CSC System.
