In a general aspect, a computer-implemented method can include receiving, at a computing device, a beacon signal including a vending device identifier and sending, to a cloud-based vending service, the vending device identifier. The method can further include receiving, from the cloud-based vending service, an indication of at least one product available for purchase from the vending device and receiving, at the computing device, an indication of a selected product of the at least one product available for purchase. The method can also include sending, to the cloud based service, a request to purchase the selected product and receiving, from the cloud-based vending service, a purchase token for the selected product. The method can still further include sending, to the vending device, the purchase token and receiving, from the vending device, an acknowledgment that the purchase token has been used to purchase the selected product.
