A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of an electronic wallet device, cause the one or more processors to:
• receive transaction information associated with a transaction at a transaction terminal;
• identify a set of candidate transaction cards to be used in the transaction,
• the set of candidate transaction cards comprising integrated circuit (IC) chips that are communicatively coupled with a card reader of the electronic wallet device,
• a first card reader interface connecting each card reader of at least two transaction cards in each card slot of a plurality of card slots,
• the plurality of card slots for holding the at least two transaction cards,
• a card slot module, removably connected to the electronic wallet device, comprising:
• a removable module hub including:
• a single card slot,
• a single card reader, and
• a second card reader interface,
• the second card reader interface connecting to the first card reader interface, and the removable module hub connecting to a hub associated with the plurality of card slots, when the card slot module is physically connected to the electronic wallet device;
• obtain card information associated with the set of candidate transaction cards;
• select a transaction card from the set of candidate transaction cards,
• the transaction card being selected based on:
• the card information associated with the set of candidate transaction cards, and
• a scoring system,
• the scoring system for determining which of the set of candidate transaction cards satisfies a threshold relative to the other candidate transaction cards in the set of candidate transaction cards;
• and
• provide a transaction token, associated with the transaction card, to the transaction terminal.

A method, comprising:

• detecting, by an electronic wallet device, a transaction pending at a transaction terminal,
• the electronic wallet device holding at least two transaction cards,
• the electronic wallet device including a first card reader interface,
• the first card reader interface connecting each card reader of at least two transaction cards in each card slot, of a plurality of card slots,
• the electronic wallet device including a card slot module,
• the card slot module being removably connected to the electronic wallet device,
• the card slot module comprising:
• a removable module hub,
• the removable module hub including,
• a single card slot,
• a single card reader, and
• a second card reader interface,
• the second card reader interface connecting to the first card reader interface, and the removable module hub connecting to a hub associated with the plurality of card slots, when the card slot module is physically connected to the electronic wallet device;
• selecting, by the electronic wallet device, a transaction card from the at least two transaction cards,
• the transaction card being selected based on a scoring system and at least one of:
• information associated with the at least two transaction cards, or
• information associated with the transaction,
• the scoring system for determining which of the at least two transaction cards satisfies a threshold relative to the other at least two transaction cards;
• obtaining, by the electronic wallet device, a transaction token associated with the transaction card;
• and
• providing, by the electronic wallet device, the transaction token to the transaction terminal.
