A caddy receivably retains a two-way messaging pager. The caddy has a connector for power and data transfer between the pager and caddy. The caddy can also be equipped with a magnetic strip card reader. This enables remote transactions using a magnetic strip card such as a credit card or debit card. The caddy has serial bus ports for attaching the caddy to peripheral devices such as printers and taxi fare meters.
