the DigiCard RFID is the latest technology in card prepayment meters. The meter is now a sealed unit, requiring customers to simply hold their cards close enough to the meter for the credit to be transferred. RFID technology makes the meter more resistant to tampering than traditional coin and card meters. This 100 Amp meter is MID approved and can be set up with two tariffs, perfect for Economy 7. Building owners can purchase payment cards, which can be sold to the end consumer to top up their meter, allowing payment to be received in advance of receiving the bill. The meters are used but not for very long so in excellent condition there are 16 meters in total, I have also got top up cards already charged and ready to go... i have 75 £5, 101 £10 and 177 £20, i also have the the unit and usb to top the cards back up but will need to get a licence to use it (around £250) or you can just buy more card as only £35 for 100 cards, i have set the meters on both tariffs at 0.38 but you can purchase a programming card for around £20 to change tariffs. i can break down to singles but will split the cards equally. any questions please feel free to contact me. thank you
