At the 28th CARICOM Heads of Government Conference in Barbados it was agreed to implement a CARICOM travel card that will be issued to every CARICOM national except those on the Community's watch list. An implementation plan for the document will be put together and submitted to the Heads at the next inter-sessional meeting to be held in September. The card will virtually maintain the 'single domestic space' and holders will not need a passport, during inter-community travel. The card will also allow a CARICOM national an automatic six-month stay in any territory within the bloc. It is not expected to affect the security of the member countries, as any holder will be deported if he or she breaks the law. Similar to the "Pass Cards" available in other parts of the world, the new card would be the size of a credit card and will feature facial and fingerprinting biometrics – so upon arrival at an airport, travellers can swipe the card in the machine which will open the barrier allowing them to walk through. The development and implementation of the CARIPASS travel card has been described by St. Kitts and Nevis Prime Minister Roosevelt Skerrit as a "major step towards hassle-free travel". In addition to being available to all CARICOM nationals, the card would be available to expatriates who have legal status in a member country. Their card would be time-bound in a way that is linked exclusively to the time of their legal status. The cost of acquiring the card is to yet be determined, but the country leaders have agreed that the proceeds would go towards offsetting the cost of enhanced security at the ports. At the 28th Conference of the Heads of Government in July 2007, CARICOM leaders discussed the issue of crime and security and agreed to the implementation of a CARICOM Arrest Warrant Treaty (CAWT) and CARICOM Maritime and Airspace Agreement which were expected to be finalized by September 2007. By April 2008, the Arrest Warrant Treaty was ready to be signed at the next annual summit in St. John's, Antigua. At the 29th Conference of the Heads of Government in July 2008 the CARICOM Arrest Warrant Treaty along with other agreements that were ready at the time (including the Agreement Establishing the Caribbean Aviation Safety and Security Oversight System (CASSOS); the Agreement Establishing Caribbean Disaster Emergency Management Agency (CDEMA); the Agreement Establishing the Caribbean Development Fund (CDF) and the Maritime and Airspace Security Co-operation Agreement) were signed by some member states, namely Antigua & Barbuda and Trinidad & Tobago.
