Daily deal vouchers can be stored from multiple sites all in one place, as well as travel portfolios, insurance policies, marriage licenses, and more.
The system allows receivers to cash out in multiple ways including via cash, pre-paid cards, vouchers, and checks.
Reference sequence numbers (BOLD) and Accession numbers (GenBank) for voucher species which were used to construct multiple sequence alignments (for I. punctatus) are listed in Table S2.
The challenge remains to standardize voucher data, so it can be tracked consistently among multiple databases.
