Designed to be fast, intuitive and secure, OPTO is a digital contactless payment solution invented by a team of scientists and engineers to simplify life in vending.

The connection with the vending machine is established automatically without NFC, but using a patented technology based on the light of the phones’ screen.

Light frequencies are easily seen by the naked eye but are almost impossible to replicate due to the presence of ambient light surrounding the signal, making it the safest choice to transmit data.

The dedicated App enables payment with any vending machine equipped with an OPTO reader, independently from the vending operator or national borders. Top-ups can be done with cash, credit cards or other electronic payment instruments.
OPTO is the start of the vending revolution!

OPTO is a free app, compatible with smartphones Android 5.0 and higher, as well as I-Phone 7.1.2 and higher.
The simplest way is to use credit cards. Top-up is instant, safe and without additional costs.
Follow the instructions included in the app about closing an account. In a few days, all available funds will be credited back to the card you used for the last top-up. If you have also a "cash wallet", talk directly to the vending operator to get a refund.
Yes, but in order to do so you must use a Promo Card (see below), which will be handed to you by the operator. By doing this, the balance of your "cash wallet" will be available only at the vending machines of that specific operator.
It is likely that you have funds in your "cash wallet", but the vending machine you want to buy from belongs to another operator: check it out. If so, top-up with credit card: the balance will be available everywhere!
Sure. OPTO does not use NFC technology, therefore any smartphone will do, as long as it is not too old!
None. The app is free, and there are no commissions on purchases or top-ups. Guaranteed!
Ask the vending operator to install OPTO in the machines at your workplace. If he doesn't know OPTO, show it and tell him to get in touch with us!
Prices are set by the operator, but it is likely that, in order to favor cashless payments, prices with OPTO are more convenient. On top, you can receive special discounts and promotions.
When you register to OPTO, an e-money account is opened at a partner bank in the European Union. Your funds are deposited safely and you can use them at any given moment.
