A coaster configured to engage another object, specifically a coaster or coaster-like device with means to attach to another object including an object with which is it meant to interact. In a preferred embodiment, the coaster contains a magnetic material capable of engaging with another magnetic componenta soft or hard magnet, an electromagnet or other magnetic materiallocated on or within another object. An additional magnet can be integrated into or attached to the coaster. The coaster can be imprinted with any number of designs, logos, or custom artwork making them an attractive vehicle for marketing efforts or imprinted with game boards or other graphics integral to user interaction with the host device.

A system for deterring the placement of a foreign substance in a user's beverage and for alerting the user to such attempts including a sensor that detects movement or agitation, such as an accelerometer, contained in a substantially flat housing, preferably configured to provide a surface on which a coaster and/or a beverage can rest. Said system includes means for the sensor to transmit data to a processor that is enabled with software capable of communicating with an external device or activating an alarm system associated with the housing.

A secure beverage container includes a body having a first end, and a second end opposing the first end. The secure beverage container includes a lid assembly to be received by the second end. The lid assembly includes a lid housing, a sipper carried by the lid housing, a latch carried by the lid housing and configured to selectively latch to adjacent portions of the body, and a mechanical assembly carried by the lid housing and coupled to the sipper and the latch. The mechanical assembly is configured to operate in one of a locked state, and an unlocked state. The lid assembly also includes an access control device carried by the lid housing and coupled to the mechanical assembly, the access control device configured to cause the mechanical assembly to switch between the locked state and the unlocked state based upon a security token.

A safety cover for a drink to prevent tampering, comprising a long cylindrical body that stretches over a drink glass in a way that is difficult to remove, high-friction features to make the cylindrical body even harder to remove from the glass, and a small opening for drinking or straw insertion that is difficult to use for unauthorized tampering of the drink.

A device for protecting against tampering includes connecting means for removably connecting the device to a vessel, and imaging means for capturing frames of one or more imaging areas while the device is removably connected to the vessel via the connecting means. The one or more imaging areas include at least one imaging area corresponding to an opening of the vessel. The device further includes processing means for detecting, based on the captured frames, a potential tampering with the vessel or contents of the vessel, and alerting means for visually indicating the potential tampering.
