Visa has revealed a darling new feature that will let consumers authorize debit transactions via song. It’s all part of Visa’s revised but always-exciting operating regulation 6.2.A.7.b, which now lets you “choose to sing to authorize a debit transaction.” Don’t worry if the merchant gives you an awkward look, they’re just sheepish about their cruddy singing skills. Sing louder to encourage them to join in the transaction-approving fun! (Thanks to Barbara!)
