yes dave, online would be bank transfer and on a phone would be similar to a terminal but with an app, you'd still need a merchant account though with the phone app. it works out quite expensive TBH. but phone payment is deffo the future, card terminals will soon be exstinct, wouldnt be surprised if you could scan a card with a phone soon or text payments etc... technology is struggling to keep up with itself at the moment. and its very hard to decide which road to go down
