In-person authentication for existing payment ecosystems.
PalmPass authenticates the person at point of sale. Existing payment gateways, banks, and merchant acquirers handle the transaction.
Important Notice: PalmPass does not hold customer funds, process monetary transactions, or operate a payment network. PalmPass is solely an identity and authentication infrastructure layer.
