If you’ve been all over town slapping your iPhone 6 or 6 Plus on the point-of-sale terminal at the stores you frequent, you might want to take a breather and check your bank statement. If you’re using a Bank of America card, you might have been overcharged. Double charged, really. It seems some back-end problems have caused some to see their Apple Pay purchases be charged twice. If you notice a double-charge, Bank of America will refund you, though.
