Tokenization As A Service
Token Schemes
Schemes in Firstoken are used to facilitate the acceptance of multiple types of data to meet the needs of each business. The scheme defines the format of the returned token and allows its existing business logic to remain intact. Token Schemes can be either multi-use or single-use. With a multi-use token scheme, the relationship between the token and input data has a one-to-one (1:1) mapping. In other words, if you send the same input data multiple times, you'll always be returned the same token value. In contrast, with a single-use (1:Many) token scheme, you would receive a new token value every time you tokenize the same data.
