Where it comes from
Cundina is what a rotating savings circle is called in Baja California, Sonora, Chihuahua and the rest of northern Mexico. Structurally it is the same institution as the tanda; the difference is regional vocabulary, and Mexicans will often tell you which part of the country someone is from by which word they use.
It is worth its own entry precisely because people search for the word they grew up with. Someone looking for help running a cundina is not necessarily going to find it under "tanda".
How it runs
An organiser gathers members, sets a fixed amount and a schedule usually matched to payday, and assigns numbers. Each round every member pays in and the member whose number has come up takes the whole pool.
The organiser collects, keeps the list, and is expected to cover any shortfall rather than let a round fail. As with the tanda, that expectation is what makes the role a matter of standing rather than administration.
Cundinas are common in maquiladora plants along the border, where large workforces are paid on the same day and a group forms easily within a shift or a department.
What makes a cundina different
The cundina's distinguishing feature is geographic rather than mechanical: it operates in a border economy where members frequently hold money on both sides of the line. A group can have members paid in pesos and members paid in dollars, sometimes the same member in different weeks.
That makes it the tradition where currency and cross-border transfer show up as an everyday problem rather than a diaspora edge case. The organiser is reconciling two currencies as a matter of routine.
Abroad
Cundinas run throughout Mexican-American communities in California, Arizona and Texas, and often span the border directly — some members in Tijuana, others in San Diego, in what is really a single community with a fence through it.
As with tandas, community organisations in the United States have run formalised versions so that participation can be documented and used to establish a credit record for members who otherwise have none.

Run your circle with the rules in the open
Njangi On-Chain keeps the tradition exactly as it is — everyone contributes on schedule, everyone takes a turn — and puts the schedule, the order, and the full history where the whole circle can see them. No treasurer holding the money.
