What it is

RK9 Labs’ JERI is a Judge Event Registration Infosystem built for tournament organizers. Its core use cases focus on card-game and competitive events, including registration, check-in, online pairings, decklist submission, live rosters, merchandise pickup, and judge penalty records. It is not a general-purpose CRM or conference ticketing tool, but a vertical SaaS product designed around on-site tournament operations.

Core features

JERI supports online player registration with credit card payments. Organizers can configure different registration tiers, such as basic entry, packages that include side events, or VIP benefits, as well as capacity limits and sold-out statuses. The system can also raise prices as the event approaches to encourage early registration. After uploading player files, JERI can automatically match and populate information during registration, and multiple player files can be merged and downloaded.

For on-site operations, JERI supports check-in via phone or tablet, and can download TDF files for import into TOM. Online pairings are published by uploading TDF files generated by TOM, and players can access them via QR codes. Decklist Creator supports online decklist creation, saving, submission, and printing, and can perform legality checks against rules. Live Roster updates dynamically based on check-ins or decklist submissions. The merchandise pickup module tracks distribution status, while the judge penalty system lets judges enter and view penalties and comments in real time.

Pricing and integrations

The main content does not disclose standard subscription pricing, per-event fees, or a free trial. Payments rely on Stripe, and organizers need to set up their own Stripe accounts. Third-party connectivity mainly consists of Stripe payments and coordination with the TOM tournament software workflow via TDF files. RK9 Labs also offers the Hive management solution, which can provide on-site equipment such as TOM computers and scanners, and assist with operations such as data flow, check-in, initialization, penalty slips, and scorekeeper supervision. However, this service costs extra and requires the team to be on site.

Pros, cons, and best-fit users

Its main strength is deep coverage of tournament workflows, significantly reducing paper-based check-in, paper decklists, and manual organization. It is well suited to medium and large event organizers, judge teams, and scorekeepers. The drawbacks are that public information lacks details on pricing, security and compliance, permission management, APIs, and support. In addition, the reliance on Stripe may affect availability in some regions.

Access from China and alternatives

Access from China is not clarified in the main content. Stripe payment collection, the English-language interface, and cross-border service delivery may create barriers to adoption. For events in mainland China, organizers may consider domestic event registration or ticketing tools, local payment forms, general event management systems, or using tournament tools such as TOM together with localized registration and notification workflows.
