The TI-307 followed the stylish TI-1786 and was introduced with the TI-305, TI-306 and TI-308 Elle using a portrait orientated calculator housing. 

Production of the TI-307 moved in 1992 to Thailand, please notice the changed colour of the keys. 

In 1989 the production of the TI-307 was started in the USA, too and it appeared as TI-7000.

The next credit card sized calculator was the TI-307+, neither its design nor its quality is exciting.

Don't miss the Casio FIML CARD SL-800, a real credit card sized calculator with a thickness of only 0.030".
