JF Cards' unique automatic trade matching process finds all possible trade combinations, including group exchanges in addition to direct trades, based on the wants of people and their offers
Group exchanges are possible when there is any combination of people who have things that each other want
Instead of any direct trade, each person in the group gets something from one person while giving something to another person
JF Cards multiplies the overall number of possible trade combinations with it's powerful group exchange matching, setting it apart from all other systems that are limited to direct trades
There is no limit to the number of people that may be included in group exchanges. The more people, the greater number of possible trade combinations
Direct Trades:
In groups of people of any size, the number of possible direct trade combinations is limited to the matching of any two people
For example, in a group of three users, there are three possible direct person-to-person matches, each involving two users
Group Exchanges:
In groups of people of any size, the number of possible group exchange combinations grows as the size of the group grows
For example, in a group of three users, there are two possible multi-person matches, each involving all three users
Adding them up:
JF Cards multiplies the overall number of possible trade combinations by adding group exchanges on top of direct trades
With the three users in our example above, we see five possible trades, including three direct person-to-person matches and two multi-person matches
With four users, we see 14 possible trades, including six direct person-to-person matches and eight multi-person matches
The number of multi-person matches increases at a rate higher than direct person-to-person matches. The overall number of matches is multiplied when compared to direct person-to-person matches alone
JF Cards allows you to shop without money
Simply list your own things that you are putting up for sale, then begin shopping by offering them as payment for other people's things
Each time any offer is made, JF Cards's automatic trade matching process goes through all other offers and finds any possible group exchange combinations
Any individual offer that is made for something may be accepted by its owner, creating a direct trade between those two people
