Yes. Laso cards can be used anywhere prepaid is accepted, including merchants that use processors like Stripe, Adyen, Braintree, and others.
However, whether your transaction is accepted is primarily determined by the merchant's own risk engine and policies, not the processor itself. Some merchants decline prepaid cards or certain transaction patterns.
If a merchant declines your card, check our merchant acceptance FAQ for tips and alternative paths (e.g., adding your card to PayPal and paying through PayPal).
