Card security is really important, when a card can be purchased by a 
landlord/building owner for 6p and can have a re sale value to the tenant 
for up to £2 and above.
Matrix Metering Ltd, are the ONLY COMPANY in the UK who sell card meters
to offer the landlord a FREE OF CHARGE card bank facility

How it works,
When a landlord purchases card meters from Matrix Metering Ltd we register
 him for the re purchase of cards. We only then sell to the registered owner. 
Matrix Metering Ltd DO NOT SELL CARDS TO ANY DISTRIBUTORS.
The integriety and security of the system is very important to us.
