Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Enfuce

  • Coverage is European, so a programme that also needs US or Asian issuing requires a separate processor and a separate integration.
  • Where Enfuce acts as the licensed issuer it takes on regulatory risk and prices accordingly, so the convenience of skipping a sponsor bank is not free.
  • European interchange caps limit programme revenue far below US levels, so business cases imported from a US card model do not survive the move.
  • It is a smaller supplier than Marqeta or i2c, which means less negotiating room on scheme fees and a thinner partner ecosystem around it.
  • Pricing is entirely quoted with monthly minimums, so low-volume programmes carry a fixed cost that does not scale down with a slow launch.
