Automation Value Cards are available in a variety of unit balances (200, 500, 1000, 10,000 units). The card number and PIN are printed on the back of the card. For security reasons, the PIN is covered with a scratch-off strip to ensure that you receive the full unit balance purchased. Since the card features unit balances and doesn't reference specific currencies, you can use your Automation Value Card anywhere in the world without concern for exchange rates or changes in the cost of services from country to country.
