Anyone thinking of getting a Chip and pin machine take a look at eMerit,
The app is free from the play store on your android phone ( not sure if they have got it on the iphone yet).
The merchant banker is Global Payments.
Its £22 + vat up front then its 3% on all transactions, 3 days and its in your bank with no monthly fees.
Had mine now for 6 months and no problems, customer love the idea of no money payments and no running to the bank to bank cheques anymore.
